[R] reading xcms files

[Roberto Olivares Hernandez]

Hi,

I am using xcms library  to read mass spectrum data. I generate objects from 
CDF files using the command line

  SME10 - xcmsRaw(SME_10.CDF)

I have 50 CDF files with different name and I don't want to repeat the command  
for each one. Is there any option to read all the files and generate a 
corresponding object name?

In advance thank you
Roberto

Something like

for(f in Sys.glob(*.CDF)) assign(sub(\\.CDF$, , f), xcmsRaw(f))

(untested, of course).
