Dear R-list, Apologies for replying late. Thanks to Andy, Dimitris, James, Uwe, Olaf, Adai, Gardar and Patrick. (Apologies if I forgot someone)
In summary: The quickest way to convert a string to an object name, seems to be by using get(dat), but it seems to work equally well if you use any of eval(parse(text=dat)) do.call("print", list(as.name(dat))) eval(substitute(print(x), list(x=as.name(dat)))) assign("dat", get(paste("dat", no, sep=""))) Thanks again, Gudrun Gardar Johannessonwrote: > Use the get() function: > > > dat99 <- matrix(c(1,1,2),3,3) > > no <- 99 > > dat.name <- paste("dat",no,sep="") > > get(dat.name) > [,1] [,2] [,3] > [1,] 1 1 1 > [2,] 1 1 1 > [3,] 2 2 2 > > > > > At 04:15 PM 8/19/2004 +0200, Gudrun Jonasdottir wrote: >>Dear R-Help list, >> >>I have a problem with convertions of strings.
