I did an update of both rstudio and my packages. I had some trouble but was
able to move a lot of the packages so most troubles seem to be behind me.
But having a problem with code that previously ran fine. See below:
require(quantmod)
Loading required package: quantmod
Loading required package: Defaults
Loading required package: xts
Loading required package: zoo
Attaching package: ‘zoo’
The following object(s) are masked from ‘package:base’:
as.Date, as.Date.numeric

Error in axis(1, at = xycoords$x, labels = FALSE, col = "#BBBBBB", ...) :
formal argument "col" matched by multiple actual arguments
lines(x[,2], col="red")
ccf(drop(x[,1]), drop(x[,2]))
How do I fix the error ?
First, find it. Use traceback() to see the stack at the time of the
call. Presumably you or one of the packages you're using has replaced
plot(), or a function that it calls, and that's the problem. Look
through the stack trace to find the culprit. You can use getAnywhere()
to retrieve the functions and to report when there are multiple copies
that might be confusing you.
