Windows XP
R 2.5.0
I am trying to produce two plots that have the same range, i.e. x from 50 to
400 on both plots and y from 50 to 400 on both plots. (This will allow me to
compare slopes). I have used the code below without success using usr (I have
also used xaxp and yaxp but I am not including the code):
plot(tgNo26[,"TGh"],tgNo26[,"TGs"],usr=c(50,400,50,400))
plot(tgNo26[grep("CONTROL",tgNo26[,"PATIENT"]),"TGh"],
tgNo26[grep("CONTROL",tgNo26[,"PATIENT"]),"TGs"],usr=c(50,400,50,400))
RESULT:
axes on first plot 50-400, y axis 50-350
axes on second plot 50-250 y axis 100-250
What am I doing wrong?
Thanks,
John
