How to pass extra argument to the function argument of do.call in R

Question

I\'d like to pass argument (stringsAsFactors=FALSE) to rbind in do.call. But the following doesn\'t work:

data <- do.ca         


        

Answer 1

do.call(rbind.data.frame, c(list(iris), list(iris), stringsAsFactors=FALSE))

would have been my answer, if it wasn't for the fact that rbind does not know what to do with stringsAsFactors (but cbind.data.frame would).

The output of strsplit is presumably a list of vectors, in which case rbind creates a matrix. You can specify stringsAsFactors when converting this matrix to a data.frame,

data.frame(do.call(rbind, list(1:10, letters[1:10])), stringsAsFactors=FALSE)
