[R] About doing figures

[Jim Lemon]

Hi lily,
As I have no idea of what the "true record" is, I can only guess.
Maybe this will help:

# get some fairly distinct colors
rainbow_colors<-rainbow(9)
# this should sort the numbers in dfm$A
dfm$Acolor<-factor(dfm$A)
plot(dfm$B,dfm$C,pch=ifelse(dfm$DF==1,1,19),
 col=rainbow_colors[as.numeric(dfm$Acolor)])
legend("bottom",legend=sort(unique(dfm$A)),
 fill=rainbow_colors)
legend(25,35,c("DF=1","DF=2"),pch=c(1,19))

Jim
