Hi,
I have a data set (data frame) approx. 50 rows * 600 columns. The columns are separated by commas. I would like to know how to remove those commas between the columns. What should I do to remove those commas?
I guess during the import of the data?
Please read the R Data Import/Export manual and the help page ?read.table. It tells you how to use the argument "sep".
Secondly, if I want only to use part of the (data frame), say (50 rows * 300 columns) instead of (50 rows * 600 columns), what should I do?
Index the data frame appropriately.
See the manual "An Introduction to R". Also, the help page ?data.frame points you to subsetting methods in its "See Also" Section.

Thanks,
Stephen
