Re: [R] Can't convert list to matrix properly

Hi! Try: myMatrix - as.matrix(myDataFrame) Looking at ?data.matrix: Return the matrix obtained by converting all the variables in a data frame to numeric mode. You could also do directly: myMatrix - as.matrix(myList) Though you might need to transpose (see ?t) HTH, Ivan Le 3/11/2010

Re: [R] Can't convert list to matrix properly

Yes, definitely! so unlist() turns the list components into a vector? What if the component are vectors, matrices etc? Thank you Miguel! - Anna Lippel -- View this message in context: http://n4.nabble.com/Can-t-convert-list-to-matrix-properly-tp1589187p1589209.html Sent from the R help
