Hello,
The first error message says:
> Error in model.frame.default(formula = r ~ tm, drop.unused.levels =
TRUE) : variable lengths differ (found for 'tm')
Please compare the size of 'r' and 'tm'.
Regards,
Pascal

Dear R-Help,
I'm using an ANOVA to determine if there is any variation that exists
between my four different shark-types and their entrance behavior towards
an apparatus.
To do this, my coding was:
df1=read.table("lemonentrance.txt", header=TRUE); df1
c(t(as.matrix(df1)))
r = c(t(as.matrix(df1))) # response data
r
f=c("Con","Bro","OEy","Bli")
k=4
n=6
tm=gl(k,1,n*k,factor(f))
tm
av=aov(r~tm)
Error in model.frame.default(formula = r ~ tm, drop.unused.levels = TRUE) :
variable lengths differ (found for 'tm')
summary(av)
Error in summary(av) : object 'av' not found
As you can see, I receive two error message, with teh second being a cause
of the first. Does anybody have any idea how I can fix this, or at least
would you happen to know what the error is referring to?
Thanks and a response would be greatly appreciated.
Kind Regards,
Craig
