Hi, I am trying to read a series of stock tickers into R, and I'm running into trouble with Ford (F) and the old AT&T (T). Read.table seems to interpret these as boolean values instead of strings, even when I set colColumns to a vector of character(0)'s. Is there a way to convince it to read them as strings? Thanks in advance for the help, David
Try this:> Lines <- "Stock+ T + F + "> DF <- read.table(textConnection(Lines), header = TRUE,+ colClasses = "character")> class(DF$Stock)[1] "character" On 7/30/07, David Rowntree <david at watermarkgroup.com> wrote:> Hi, > > I am trying to read a series of stock tickers into R, and I'm running > into trouble with Ford (F) and the old AT&T (T).
