Hi all, I am trying to write a script that will compute Kendall's tau for a 75 time series (using the Kendall package) and will then write the tau and p values from the Kendall test to a text file table that can be read into Excel. I am having no problem calculating Kendall's tau and the associated p value for each time series, but I am having trouble figuring out how aggregate the results from all the the time series into one table. For one thing, the tau and p outputs from the Kendall function don't seem to be variables that have been created in the workspace (i.e. if i type 'tau' in the command line, i get an error saying "Error: object 'tau' not found"). Is there a way I can access these values to write them to a table? When I try to write the output of the Kendall function to a table using 'write.table' I get this error message: Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors stringsAsFactors) : cannot coerce class '"Kendall"' into a data.frame Secondly, once I am able to access the tau and p values, what would be the best to write into the loop function to add the tau and p values calculated from each iteration of the loop to a table? Thank you.
