How does one track down the error message Error in deparse1(call)

Question

This code worked great:

Data <- read.csv("./input/DataSet05.csv", header=T, colClasses='factor')

Groups <- DataSet05[6:12]

Groups[Groups=="0"] <- NA

rules <- apriori(Groups, parameter = list(ext = FALSE, minlen=2, supp=0.2, conf=0.5))

inspect(rules)

I updated my box yesterday, now I get the following error.

Error in deparse1(call) : could not find function "deparse1"

Also, I added some new packages.

My thoughts are the update killed the ability of arules to work.

QUESTION

How do I track down this error message to identify why the R code no longer runs?
