Reshaping several variables wide with cast

Question

I have a data.frame that looks like this:

> head(ff.df)
  .id pio caremgmt prev price surveyNum
1   1   2        2    1     2         1
2   1   2        1         


        

Answer 1

You can do this with the reshape function in base R. The column ordering is a little weird, but can be fixed easily.

 reshape(ff.df, direction = 'wide', idvar = "surveyNum", timevar = '.id')
