DynareR is an R package that can run Dynare program from R Markdown.
Users need the following in order to knit this document:
-
Dynare 4.6.1 or above
-
Octave 5.2.0 or above
-
Dynare is installed in the standard location as follows:
-
/usr/lib/dynare/matlabforLinux -
/usr/lib/dynare/matlabformacOS -
c:/dynare/x.y/matlabforWindows, wherex.yisDynareversion number.
If dynare and Octave are installed in standard location, DynareR
package will take care of the configurations, which include adding
matlab directory to path, using the latest installed dynare and so
on. Otherwise, users have to specify the matlab folder using
add_path function, set the Octave path using the set_octave_path
function, or set dynare version using the set_dynare_version
function.
DynareR can be installed using the following commands in R.
install.packages("DynareR")
OR
devtools::install_github('sagirumati/DynareR')Please load the DynareR package as follows:
```{r DynareR}
library(DynareR)
```
Then create a chunk for dynare (adopted from Dynare example file
bkk) as shown below:
```{dynare bkk,eval=T}
/*
* This file implements the multi-country RBC model with time to build,
* described in Backus, Kehoe and Kydland (1992): "International Real Business
* Cycles", Journal of Political Economy, 100(4), 745-775.
*
* The notation for the variable names are the same in this file than in the paper.
* However the timing convention is different: we had to taken into account the
* fact that in Dynare, if a variable is denoted at the current period, then
* this variable must be also decided at the current period.
* Concretely, here are the differences between the paper and the model file:
* - z_t in the model file is equal to z_{t+1} in the paper
* - k_t in the model file is equal to k_{t+J} in the paper
* - s_t in the model file is equal to s_{J,t}=s_{J-1,t+1}=...=s_{1,t+J-1} in the paper
*
* The macroprocessor is used in this file to create a loop over countries.
* Only two countries are used here (as in the paper), but it is easy to add
* new countries in the corresponding macro-variable and completing the
* calibration.
*
* The calibration is the same than in the paper. The results in terms of
* moments of variables are very close to that of the paper (but not equal
* since the authors a different solution method).
*
* This implementation was written by Sebastien Villemot. Please note that the
* following copyright notice only applies to this Dynare implementation of the
* model.

The above chunk creates a Dynare program with the chunk’s content, then automatically run Dynare, which will save Dynare outputs in the current directory.
Please note that DynareR uses the chunk name as the model name. So, the
outpus of Dynare are saved in a folder with its respective chunk name.
Thus a new folder bkk/ will be created in your current working
directory.
By default, dynare chunk imports log output as a list of dataframes,
which can be accessed via dynare$modelName. Therefore to access the
outputs of the bkk model produced by the dynare chunk, use
dynare$bkk.
Use inline code `r dynare$bkk$moments[2,3]` to access the value of
second row and third column of the moments, which is 0.0024.
The Impulse Response Function (IRF) is saved by default in
bkk/bkk/graphs/ folder with the IRF’s name bkk_IRF_E_H2.pdf, where
bkk is the Dynare model’s name. Therefore, you need to add
stoch_simul(graph_format = (pdf)) to change the default saving
behaviour of Dynare from eps to pdf.
The DynareR package is also designed to work with base R. The following functions show how to work with DynareR outside the R Markdown or Quarto documents.
Use this function to embed the graphs Impulse Response Function (IRF) in R Markdown or Quarto document.
The Impulse Response Function (IRF) of the bkk model can be fetched
using the following R chunk. Note that only the last part of the IRF’s
name (E_H2) is needed, that is bkk_IRF_ is excluded. Also note that
out.extra='trim={0cm 7cm 0cm 7cm},clip' is used to trim the white
space above and below the IRF.
```{r IRF,out.extra='trim={0cm 7cm 0cm 7cm},clip',fig.cap="Another of figure generated from Dynare software"}
include_IRF("bkk","E_H2")
# Alternatively, use the path argument
```
include_IRF(model="bkk",IRF = "E_H2")
# Alternatively, use the path argument
include_IRF(path="bkk/bkk/graphs/bkk_IRF_E_H2.pdf")However, Dynare figure can only be dynamically included if the output format is pdf as Dynare produces pdf and eps graphs only.
This function writes a new dyn file.
Use write_dyn(code="code",model="someModel") if you want the Dynare
file to live in the current working directory. Use
write_dyn(code="code",model="path/to/someDirectory/someModel") if you
want the Dynare file to live in the path different from the current
working directory.

knitr::kable(dynare$bkk$autocorrelation) On Windows, you can set the version of dynare you want to use. By
default, DynareR package does this for you if the dynare version
ranges from 4.6.1 to 9.9. However, if you are using the development
version of dynare, for example version
6-unstable-2022-04-03-0800-700a0e3a, you can override the default as
follows
set_dynare_version("6-unstable-2022-04-03-0800-700a0e3a")You can use this function if Octave is not installed in the standard
location
set_octave_path('C:/Program Files/GNU Octave/Octave-6.4.0/mingw64/bin/octave20.exe')This function is a wrapper of addpath in Octave. If dynare is not
installed in the standard location, use this function to add the
matlab subdirectory. By default, DynareR does this for if dynare
is installed in the standard location.
add_path('/usr/lib/dynare/matlab')# Default for Linux
add_path('c:/dynare/5.1/matlab') # Default for Windows, but 5.1 can change if later version of
