Hello everyone, i'm new to R programming and dendrochronology. I'm trying to calculate correlations between monthly precipitation averages and tree growth (tree ring data) using the dcc function. the problem is, I'm getting an error message: Error in is.finite(if (is.character(from)) from <- as.numeric(from) else from) :

default method not implemented for type 'list', and I don't know what it means. Can someone advise on both the meaning and the solution?
