Hello all,
I am an undergraduate student who is having syntax issues trying to get
error bars on my graph.
This is the data, which I assigned the name Saline to.
Time Average SEM
1 -20 0.00 0.000
2
330 0.00 0.000
445 3.227902
you can't refer to an argument within a function call. Try
uiw - Saline[,3]
plotCI(x=Saline [,1],y=Saline [,2], uiw=uiw, liw=uiw, err=y, pch=21,
pt.bg=par(bg), cex=1.5, lty=1, type=o, gap=0, sfrac=0.005,
xlim=c(-21,340),xaxp=c(-20,320,11), xlab=Time (min), ylim=c(0,12),
yaxp=c(0,12,11),
Thanks for the suggestion...but R still doesn't like it. Now I have 3 error
messages. It seems to dislike my *err=y* command. I'm going to continue
trying. Thanks for your help! If you happen to spot anything else, please
let me know!
thanks!

Dear Beloitstudent;
Although Ben Bolker will have to give you the
definitive answer, the following will do what I
think you want to do.
library(plotrix) #for those of us who don't know where plotCI comes from
#give us the data:
Saline - structure(list(Time = c(-20L, NA, 30L, 45L, 60L,
5 matches
