Hi,
I'm a SAS user trying to convert myself to R but I still have problems with
some pretty simple commands.
First I wanted to add up a number of red-tailed hawks seen per day (julian day)
per year. So I tried:
RTyrday <- tapply(RThr,list(year,julian),sum)
And then I tried the following regression:
mod1 <- glm(RTyrday~julian+year, family=gaussian (link=identity),data=RT)
Wich didn't work since my vector RTyrday and julian don't have the same length.
My question is: How can I create a new data sheet with the output of my
function "tapply" ? Something I could have done in SAS by giving an "output
out" to my "proc summary"
Thank you,
Emilie
