Hi all,
I have been using 'source(filename)' to load R code from a file
object. However, now I have a special case where I don't have a file
since I am loading an R script from a Jar file. I would like to avoid
creating temporary files. Is there a way to use the 'source' command
with a Java String? Are there any other, better ways to do that?
source(x) is basically the same as eval(parse(x)) with bells and
whistles added. Since parse() accepts a text= argument that is an R
character vector, you could do what you want by converting your Java
string to an R string and calling eval and parse directly.
Alternatively, if you need the bells and whistles, you can use
textConnection to create a connection from an R string and source() that.
