Your problem is that you are using cat() on a factor. Use as.character() or format() to convert the factor to character data, which cat will then print in the way you want.
> x <- data.frame(L=letters[1:3]) > x L 1 a 2 b 3 c > x$L [1] a b c Levels: a b c > cat(x$L, "\n") 1 2 3 > cat(as.character(x$L), "\n") a b c > cat(format(x$L), "\n") a b c > Hu Chen wrote: > sorry, pressed "sent" by mistake. > for example > >>data <- read.csv("data.txt") >>single > > V1 V2 > 1 YHR165C CG8877 > 2 YJL130C CG18572 > 3 YDL171C CG9674 > 4 YKR054C CG7507 > 5 YDL140C CG1554 > 6 YLR106C CG13185 > 7 YGL206C CG9012 > 8 YNL262W CG6768 > 9 YER172C CG5931 > > >>typeof(data) > > [1] "list" > >>for (i in 1:nrow(data)){ > > cat(data[i,1] > } > > it'll not return things like "YHR165C" but number like 6,7,9.. > is this a new feature of list? how to turn off it. > thanks > > On 10/23/06, Hu Chen <[EMAIL PROTECTED]> wrote: > >>for example >>data <- read.csv("data.txt") >>typeof(data) >>[1] "list" >>for (i in 1:nrow(data)){ >> >> > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
