Hi again all, Several replied ASAP that I also needed reshape loaded and not just reshape2. Hmmm tried that and I had some output but not the correct format. What I need is to run simulations of time overlap between species as per the simulation program data input constraints: The basis for the simulations is a species by _time-use matrix in which species are arranged in rows, and time intervals are arranged chronologically in columns.___ TimeOverlap only uses text tab-delimited files with no headings for columns or rows.Empirical data must be specified in proportional abundances (0 to 100) and totals for each species should be the same (100%). With the existing code the result was rows were correct for species but dates were used for columns rather than the times. The input file read has long format 4 columns - species; location; date; time. It dawns on me I may need to have a sub sample of the main data set by Location ID first then have the code run but for time values and not dates. I need to tweak this a bit more to see if I can figure that out as well. I will have many repetitions of this dat reformatting so it is important I get the code correct one time so I can run this on the gazillion or so data sets accumulated. Rather than use reshape can I use _recast_ in place of cast and stick with reshape2? Bruce [[alternative HTML version deleted]]
Bruce, I'm not sure what's going on since I tried this on my Linux system running R 3.0.0 and just did: library(reshape2) help(cast) and the help for 'cast' came up. There was no indication to me that 'reshape' was needed and I can not see a dependency in CRAN for 'reshape'. But I built R from source when installing R 3.0.0 and all the packages I use had to be reinstalled... Great research, BTW!

Interestingly enoughhelp(cast) did not work but ?cast does As Ista says, there is no cast() in reshape2 John Kane Kingston ON Canada> -----Original Message----- > From: tea3rd at gmail.com > Sent: Wed, 5 Jun 2013 11:55:43 -0400 > To: neotropical.bats at gmail.com > Subject: Re: [R] reshape2 issue continued > > Bruce, > > I'm not sure what's going on since I tried this on my Linux system > running > R 3.0.0 and just did: > > library(reshape2) > help(cast) > > and the help for 'cast' came up.
