Question

 Is it possible to use a where clause within ggplot?

diamonds[1:5,]
#   carat     cut   color  clarity    depth  table   price         x    y    z
# 1  0.23   Ideal       E      SI2     61.5     55     326      3.95 3.98 2.43  

I want to use some type of conditional statement against a CSV read file.

You can use the subset function to filter rows from a data frame:

goodDiamods <- subset(diamonds, cut=='Good')
