library(reshape2)
?cast
Use acast or dcast depending on whether you want vector/matrix/array
output or data frame output.

Hello,
cast is in reshape library. Is it loaded?

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:

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
There is indeed a ?cast help topic in reshape2, but there is no cast
function. Instead there is dcast (returns a data.frame) and
acast(returns an array).
Bruce, you can try your original example with
input.cast - dcast(input.melt, Species ~ Date, fun.aggregate = sum)
Best,

As Ista says, there is no cast() in reshape2

Hi again all,
As the original code lines I had dated back to 2007 that may have
predated reshape2?
In any case the use of *dcast *rather than /*cast*/ solved the issue.
Then with 3 steps:

I saw I just needed to change the line
input.cast - cast(input.melt, Species ~ *Date*,
Yes , I think it was only a year or two ago that the change occured.
