Dear R users,
I have a dataframe with one character field, and I would like to create two
new fields (columns) in my dataset, by spliting the existing character
field into two using an existing substring.
... something that in SAS I could solve e.g. combining substr(which I am
aware exist in
> x <- 'dfabcxy'
> strsplit(x, 'abc')
[[1]]
[1] "df" "xy"

see sub() and gsub(), but it won't be straightforward as somethink like
"string(dataframe)", ie you'll have to 1st treat the character object with
sub() or gsub() and 2d rebuils a dataframe.
hope this helps
Florence.
