Hi all,
I want to represent two categories with one color and have other categories
a different color on a bar plot.
I can do this using for one category/number using the ifelse call in col but
how to extend to two categories/numbers?
barplot(dataframe$vector_o_numbers, col=ifelse(dataframe$vector_o_numbers ==
00, "red", "black"), names.arg=dataframe$labels)
For example if I wanted to label 00 and 01 red and have the rest of the
categories colored black....how to do this?
Finally........I'd Iike to put a line on the bar plot representing an
expected number to compare to the observed number for a particular category.
In the past I've done this by drawing a line manually on a graph using
photoshop or something similar. Is there way to do this in R?
Many thanks all in advance for your help!!
John
