inconsistency with cor() - "x must be numeric"
Howdy,
I have written a small function to generate a simple plot and my
colleague is having an error when attempting to run it. Essentially I loop
through categories in a data frame and take the average value for each
category The categories are in $V1, subset first then mean taken and
concatenated to previous values using rbind(c("label",mean(data$V6)). The
result is a two-column
