splitstackshape

Online data collection tools like Google Forms often export multiple-response questions with data concatenated in cells. The concat.split (cSplit) family of functions splits such data into separate cells. The package also includes functions to stack groups of columns and to reshape wide data, even when the data are "unbalanced"—something which reshape (from base R) does not handle, and which melt and dcast from reshape2 do not easily handle.
