Subject: [R] error bars
Hello R-help,
I am using R version 2.15.1.
I upgraded from R version 2.13 a few months back.
Previously, I was able to plot error bars on an xy scatter
plot using the errbar function:
errbar(RAEthylene$TIME,RAEthylene$AVE,RAEthylene$AVE+RAEthylen
e$STD,RAEthylene$AVE-RAEthylene$STD,add = TRUE,lty=2,pch=17);
Today, I went to update my plot.
However, in R version 2.15.1 I get error code saying that
this function cannot be found:
Error: could not find function "errbar"
I would perfer to avoid using the xy.error.bars<-function(x,
y, xbar, ybar) coding for these error bars, as I have many
data to put on one plot.
I've searched the .pdf file for R 2.15.1 version and cannot
find any updates for this function.
Do I have to reinstall version 2.13 again??
I need to generate these plots today!!
Please advise.
Regards,
Franklin
