R help - Feb 2013 - colors to pie chart.

hello, all.

i am trying something new and am stuck.  i typically go with whatever colors the
pie function pops out, but i would like to customize it.

please find below a sample dataset.

##TVs per household.
TVs <- factor(c(rep("0", 1), rep("1", 16),
rep("2", 14), rep("3", 12), rep("4", 3),
rep("5", 2), rep("6", 2)))

##this runs just fine.
pie(table(TVs))

##however, when i add:
colors <-
c("cyan3","magenta","darkblue","darkmagenta","darkred",
"darkgoldenrod1", "deeppink")

##and then:
pie(table(TVs, col=colors))

i receive this error.

Error in table(TVs, col = colors) : 
  all arguments must have the same length

i have tried it a few different ways (changing color names, adding cex
arguments, etc), with same results.

i am not sure why i would be getting this message if it works without the color
functionality.  i did a quick search which yielded nothing of value.

thanks in advance.

Did you try changing position of parentheses?

pie(table(TVs), col=colors)

col is parameter for pie not for table.
