Reading characters using read.table()
Thanks a lot !
By using
> var_read.table("file",colClasses=c("character"))
R returns a data.frame with characters in it.

I need to read a vector containing names of different variables from a text file (a unique column). Among them one is called "T". When I use the function read.table with default arguments and when I call the element of the data frame corresponding to name of this variable it returns me the logical value "TRUE" whereas I was expected it to return the character "T". Is it possible to specify the type data expected in a data frame when using the read.table function in order to make it unable to interpret "T" as "True" ?? Or is there any other functions enabling to import text data from a text file ??
Yes, see the help page and argument colClasses. Yes, I would have used scan().
