Hi
Copy your messages to r help, others may give you better advice.
Strange, I do not get such error. Beside, from
m = t(matrix(data = detrend, nrow = 30))
I expect matrix result, but your str shows that m is list.
> m<-list(a=rep(NA, 20), b=rep(1,20))
> colMeans(m, na.rm=T)
Error in colMeans(m, na.rm = T) :
'x' must be an array of at least two dimensions
So as colMeans help page clearly states, it expects as input
an array of two or more dimensions, containing numeric, complex, integer or
logical values, or a numeric data frame. For .colSums() etc, a numeric, integer
or logical matrix (or vector of length m * n).
I fish in murky waters. If you fail to provide enogh information you cannot
expect reasonable answer.
My guess is that your original data are not what you think they are.
Cheers
Petr

Hi
The errors are self explanatory. Function needs to be fed by numeric values.
What is the result of
str(m) or str(detrend)
Cheers
