[R] Creating a correlation Matrix

[Wiener, Matthew]

It looks like you have missing observations.  With the "use" argument, you
can specify complete observations or pairwise-complete observations.

Hope this helps,

Subject: Re: [R] Creating a correlation Matrix


I've tried using cor() by the following sequence:

C <- cor(x, y = NULL, use = "all.obs", method = c("pearson"))

where x is my matrix of 21 columns and 3471 rows.

and I get this error:

Error in cor(x, y = NULL, use = "all.obs", method = c("pearson")) :
         missing observations in cov/cor

any suggestions?
