hi,
new to R and using the car package to do some scatterplots with ellipses
hoping to add the area and center points of each ellipse to the legend?
looking for some direction / ideas.... here is the script, the data is
where
golf shots end up by club.
x (dispersion), y (distance), group (Club)
thanks, sam
## usage: Rscript shotScatter.R infile outfile level1 level2 minX maxX
minY maxY
## load the library
library(car)
## get the args
args = commandArgs(TRUE);
## get the data format is: x, y, group
Shot_Data <- read.table(args[1],
sep = ",",
header=T)
## setup the pdf file name
pdf(file = args[2])
## do the plot
scatterplot(y ~ x | Club, data=Shot_Data,
ellipse = TRUE,
levels = c(as.numeric(args[3]), as.numeric(args[4])),
robust = TRUE,
boxplots = "",
xlab = "Dispersion",
ylab = "Distance",
xlim = c(as.numeric(args[5]), as.numeric(args[6])),
ylim = c(as.numeric(args[7]), as.numeric(args[8])),
smooth = FALSE,
reg.line = FALSE)
