Hi,
I know this is probalby a very trivial thing to do for most of the R
users, but since I just strated using it I have some problems....
I have a data.frame with a field called "razred". This field has
values from 1 up to 15.
Is it possible to create a for loop that would create a new data
frame for each of the "razred" values.
The R-way would be to use the split function and leave the result in a
list to which the same operation could be also repeatedly performed
using lapply.
?split
And take a look at the fourth example applying split to the builtin
airquality dataframe.
The plyr package also provides functions on dataframes.
