I would really appreciate it if anyone could determine what is going
on with the following command. It is only half-working and is losing
lots of data. For the life of me I cannot even see the pattern of what
it is losing and what it is not.
I am attaching the R data set which you can use with the Load
Workspace menu function.
WideICA<-reshape(ICA,v.names=c("OD","Thickness","Surface.Cover"),idvar=c("Strain","ica","Rep","Locations"),drop="Growth",timevar="Time",direction="wide")
The following two commands should give the same data (other than the
missing values) but they do not.
ICA[ICA$Time==6,"Surface.Cover"]
WideICA$Surface.Cover.6

Thank you very much Hadley. I still do not know why my original reshape command did not work but for the "price" of a library download I was able to solve my problem wonderfully. Thank you for salvaging many hours of work. The melt and cast concept is wonderful and simple Farrel On 11/29/06, hadley wickham <h.wickham@gmail.com> wrote:> > You may want to try the reshape package, http://had.co.nz/reshape, > instead.
