I'm reading in some data from a csv file, and it's reading in some of the columns as character variables instead of numeric. I know I can fix this by doing as.numeric for each of the columns, but the problem is I have a LOT of different quantitative variables that I would have to do this for. I've been trying something along the following but it hasn't really been working >columns<-c(1,4,6,8,20,22) # where these are the columns that are numeric workf is the data matrix that I'm working with So I tried >workf[,columns]<-as.numeric[,columns] when I do this I get the error message Error: (list) object cannot be coerced to type 'double'
I've tried doing it different ways, with a new data matrix Matr and doing >Matr<-workf >Matr[,columns]<-as.numeric[,columns] but it keeps on bringing up the same error message. Could someone help me with this?
