Re: [Gretl-users] Problem storing scalars

Dear all,
I need to save the R_squared into a file outside gretl, and my guess is
there is a problem on how to store scalars.
Suppose I run a simple panel regression:
panel Y const X
Then, to retrieve the R_squared I use the command:
genr R2 = $rsq
which work fine as a get the message: "Generated scalar r2 = 0.89778".
First of all, did you use R2 or r2, and consistently?
Now, in order to store this in a file, untill few weeks ago I was using
the store command, in this way:
store --csv path_to_myfile/my_file r2
However this does not work anymore, as I receive the following error
message: " 'r2' is not the name of a series "
Is something changed in the way scalars are dealt with ?
You could use the outfile command to redirect the output into a text file:
outfile --write path_to_myfile/my_file
print r2
outfile --close
or you could convert the scalar to a matrix, something like this:
matrix tostore = {r2} # maybe also/only works without the braces?
mwrite(tostore,'path_to_myfile/my_file')
hth,
