Title: R error: formal argument "col" matched by multiple
Post by Algo Designer on 01/21/12 at 11:19:41

After updating xts package in R, I encountered the following problem:

Code:

> plot(equity, col = "blue")
Error in axis(1, at = xycoords$x, labels = FALSE, col = "#BBBBBB", ...) :
formal argument "col" matched by multiple actual arguments

Here is a workaround:

Code:

> plot(equity)
> lines(equity, col = "blue")
