Hi, See that strsplit() retorns a list object. Then, to transform a character vector (that is an element into the list), to a numèric vector, you should access directly to that element to aply as.numeric. The code is:
aux<-"0.5 1 2 3 4" vectnum<-strsplit(aux," ") class(vectnum) ## see that is returning a list numaux<-as.numeric(vectnum[[1]]) ## get the nummerical vector form the vector object that stays into the vectnum list Message: 20 Date: Wed, 25 Mar 2015 10:27:40 -0700 (PDT) From: Turgidson <e...@upenn.edu> To: r-help@r-project.org Subject: [R] Converting charter string to vector of numbers Message-ID: <1427304460123-4705097.p...@n4.nabble.com> Content-Type: text/plain; charset=us-ascii Apologies for bringing up an old topic, but I am not finding working answers. I am also an R newbie, so I'm still on the steep part of the learning curve. I have a character string : "0.5 1 2 3 4" I need to convert it to a vector of numbers. I get as far as strsplit(), which gives me "0.5" "1" "2" "3" "4" this is still treated by R as a single item. I need to get it to look like this: "0.5", "1", "2", "3", "4" so that I can use as.numeric() and make it into a vector of numbers... I have been going mad because for text operations, commas and quotes are loaded with meaning, and I keep going around in circles.
