[R] error at R CMD check

[carol white]

Hi,
I generated an R package but at running R CMD check, I got the following error message for the first data file:

*** installing help indices
 >>> Building/Updating help pages for package 'jamda'
     Formats: text html latex example 
  f1                           text    html    latex   example

  f6                      text    html    latex   example
too many pairs of braces in file 'data1.Rd' at /usr/lib64/R/share/per
l/R/Rdconv.pm line 295, <$rdfile> line 7076.
ERROR: building help failed for package ‘my_package’

Should the data sets be in a specific format? Mine contains data in float seperated by tab with column names and row names. No description in DESCRIPTIOn file yet.

Thanks 

Carol
