Hi r-help-bounces at r-project.org napsal dne 07.07.2009 09:54:30:
Hi everyone, Hi want to separate the string(column1) for example
Well, how did you get the data in R? Are they in separated columns of data.frame? What do you mean by "separate"?
column1 column2 column3 column4 column5 column6 bear b e a r cat c a t tiger t i g e r I know how to do this in excel where using MID function.
As Microsoft is more user friendly and uses translated functions in language specific versions of Excel I do not have function MID. I suspect it takes values from middle of string set by some identifiers. If it is the case see ?substr However I would start with ?read.table and related read.* functions to get the data into R in appropriate shape. Regards Petr
Now I want to solve it using R. The list of strings is in text file. I looked up the help but did not find it. Can someone help me here? Thank you very much. Regards, Hema [[alternative HTML version deleted]]

Hi
If you have data frame like this
test=data.frame(x=c("abcd", "abc", "abcde"))
than
strsplit(as.matrix(test), "")
makes a list with splitted character vectors. If you want them in data
frame you would need to combine vectors of unequal length.
However I would try reading your text file with
read.fwf(file, 1)
Regards
Petr

Hi Petr, The data in text file and not csv format. The word "separate " which I mean in this content is like split/separate
the
string to each alphabet where each alphabet will be in different column. thanks alot. regards, Hema.
