OK, I need help plotting. I have column headings of Day, Wgt, Foodin, Rep,
Grp and Tanks. Rep=c(1,2,3) and Tanks=c(a1,a2,a3,a4,a5,a6,
c1,c2,c3,c4,c5,c6, h1,h2,h3,h4,h5,h6).
I created a subset where I only would like Rep=2, and Tanks=c(a4,c4,h4) and
would like to graph (points) of Wgt and Day. I would think that I only need
3 colors, but when I run with only 3, only 2 lines show up. When I add a
4th color (pink in this case), I get the 3rd line. If I subset for
c(a1,a2,a3), it works using three colors. Should be simple, but I dont see
it.
rm(list=ls())
daily<-subset(raw, subset=Foodin>1 & Rep==2 & Grp=="fed" & Tanks=="a4"|
Foodin>1 & Rep==2 & Grp=="fed" & Tanks=="c4"|Foodin>1 & Rep==2 & Grp=="fed"
& Tanks=="h4")
attach(daily)
x11()
par(cex=1.4)
plot(Day, Wgt col=c("red","blue","purple","pink")[Tanks])
detach(daily)
