I am just learning to use qplot and can't get the fill/colour to work. Below
is the R code for a scatter plot and bar graph.
library(ggplot2)
x<-c(1,2,3,4,5,6,7)
y<-c(1,2,3,2,5,6,3)
qplot(x,y, main="Scatter Plot Test", xlab="X Label Test",
ylab="Y Label
Test", colour="blue")z<-c("van", "van",
"van", "car", "car", "truck",
"truck", "truck", "truck", "van",
"van")
qplot(z, main="Bar Graph Test", ylab="Vehichle Count",
xlab="Vehicle
Category", fill="blue")
If I set fill=z, then I can get something different, i.e. three preselected
colors are used, but what if I want all three bars to just be blue instead
of the default?
I am having the same issue if I try to use colour. How do I change the
default color to blue instead of black.
Second question what exactly is the difference between colour and fill?

One difference between colour and fill can be demonstrated by specifying both with different values. In cases where a polygon is filled, colour specifies border line color.
