Hi I'm just starting off with R but is this correct?
I have this data set.
> data
Type ID Size
1 Reqd 244808 1024
2 Reqd 244045 512
3 Reqd 245427 800
4 Reqd 245423 1024
5 Reqd 244983 1024
6 Used 244808 615
7 Used 244045 33
8 Used 245427 261
9 Used 245423 461
10 Used 244983 1194
I want a scatterplot of the Size values grouped by the Type column.
I also want 2 lines showing each group's "average".
> library(ggplot2)
> data <- read.table("mem.dat", header=T, sep=",")
> attach(data)
> ggplot(data.frame(Type, ID, Size), aes(x=ID, y=Size, shape=Type, color=Type))
+ geom_point(shape=1) + scale_fill_hue(l=40)
+ geom_line(stat="hline", yintercept=mean, linetype="dashed")
