In cases where there are R objects with different frequencies, it would be better to treat the RDATA file as an EViews Database instead. You can also open a pre-existing RDATA file as an EViews workfile, though because this operation can only open all R objects into a single workfile page, all the objects in the RDATA file must be the same frequency for this to work properly. This means you can save an EViews workfile (one page at a time) directly to a new RDATA workspace file: wfsave( type =rdata) c:\files\tq.rdataĮach simple object (series, alpha, matrix, vector, and scalar) on the current workfile page will be converted to an appropriate R data structure and saved into the new RDATA file. Once we've completed our R operations, we can close our connection with a simple call to XCLOSE: XCLOSEĪbility to Save EViews Workfile as RDATA Workspace FileĮViews also has native RDATA workspace file compatibility. To retrieve data back into EViews, we will use the XGET command: XGET(name=beta, type=vector) z $coef Thus, to display the contents of a matrix X, you must issue the command XRUN print(X) To instruct R to show all of the output, you should use enclose your command inside an explicit print statement in R. In the most extreme case, you may see a simple "OK" message displayed in your log window. Consequently, you may find that using XRUN to issue a command that displays output in R may return only a subset of the usual output to your log window. Note that our connector does not always automatically capture all of your R output.
XOFF ' Turn off external programming mode Z < -glm(y~x1+x2, family= Gamma(link= log), data= vars) summary( z) Use XOFF (or XCLOSE) to turn this mode off. Once you call XON, all command lines after that will be sent to R directly. To run multiple R commands without having to specify XRUN on each line, you can use the XON and XOFF commands (introduced in EViews 10) to control external programming mode. Now that we have some data in R, we can run R specific commands by using the XRUN command: XRUN z < -glm(y~x1+x2, family= Gamma(link= log), data= vars)
EVIEWS 10 SERIES
As our example shows, XPUT also supports grouping mul- tiple series objects into a single R time series or R ame object. Depending on the EViews object type, an appropriate R object will be created when the data is sent. Now that we have an open connection to R, we can send EViews object(s) to R using the XPUT command: XPUT(rtype=ame, name=vars) y x1 x2īasic EViews object types such as series, alphas, matrices, vectors, and scalars can be pushed successfully to R.
Now that we have an open connection to R, we can use the other 'X' methods to perform some actions. This log window will show any R commands we run and any output generated by R.
This will begin a new session of R and, by default, an associated RConn Output log window should appear. Otherwise, an R ame structure will be created instead.Īll external program interface methods must begin with a call to XOPEN: XOPEN( type =r) If you select "ts (time series)", series objects that have a compatible R ts frequency will be pushed as R ts objects. Optionally, you can also select your Save Series as preference when pushing EViews series objects into R. "R-3.2.3") under the parent R folder as your home directory. Select the version-specific R folder (e.g. Next, if Home Path is blank, click the button and navigate to your local R installation. In COM ProgID group, make sure that EViewsRConn.VariantRConn is selected for R.
