Hello, everyone
I run Eclipse Ganymede and R 2.7.2 at work.
I have one R script file where I open in memory a new xls file (using
xlsReadWritePro), call other R scripts, which are in the same folder
as the main R script,
which get data from an existing xls file, process data, and output
results in the xls file which is in memory.
That is the idea. But I cannot make it work.
First, I do not really know how to call other R scripts from an R
script.
I am using function source like this: source(file="G:/data/
datafile.xls")
The source function is for reading files that are valid R code, not
for reading data files.
I get a following error (in German, as I work with German Windows):
Converting xls file to csv file... Fehler in system(cmd, intern =
!verbose) : perl nicht gefunden
Fehler in file.exists(tfn) : ungültiges 'file' Argument
Basically it says:
Converting xls file to csv file...Error in system(cmd, intern =
!verbose) : perl not found
Error in file.exists(tfn): invalid 'file' Argument
What is wrong?
How can I call and execute R-scripts from another R-script?
"source" would be the way, but you should be offering it .R files,
rather than .xls files.
There are other functions designed for reading external data files.
See the Import/Export Manual.
