[R] Creating a dataframe from several numeric and character vectors

[Sven Garbade]

Hi all,

I want to combine some numeric vectors and one character vector to a
dataframe and did this:

    dat <- cbind(type, key,response, st)
    dimnames(dat) <- list(NULL, labels)
    dat <- data.frame(as.numeric(dat$"type"),
as.numeric(dat$"key"),                                            
as.numeric(dat$"response"), dat$"st")

where st is the character vector. I got this error:

Error in "names<-.default"(*tmp*, value = vnames) : 
	names attribute must be the same length as the vector

If I only type

    dat <- data.frame(dat)

then all variables are factors. I need all variables as numeric except
st. How can I do it?

Thanks, Sven
