problem with abline
...so get no error. I arm using V 2.10.0 on Windows 7.
Here is my code, including the SAS transport file import:
require (foreign)
require (chron)
require (Hmisc)
require (lattice)
clin <- sasxport.get("y:\\temp\\subset.xpt")
attach(clin)
plot.new()
xyplot(jitter(b.lvef)~jitter(log.fgf),
main="Scatter Plot of Baseline Ejection Fraction\nby Log10 FGF-23",
ylim=c(10,90),
ylab="Ejection Fraction", xlab="Log10 FGF-23")
abline(lm(b.lvef~log.fgf))
Any suggestions appreciated.
Thanks,
Gerard

Removing trailing spaces

discussion about a simple method of removing trailing spaces from

can't find any mention of anything like it in the R archives or with
help.search().
There are ways I could do it with substring(), but I seem to remember
there was something more elegant.

creating standard curves for ELISA analysis
Hello R guru's
I am a newbie to R, In my research work I usually generate a lot of ELISA
data in form of absorbance values. I ususally use Excel to calculate the
concentrations of unknown, but it is too tedious and manual especially when
I have 100's of files to process. I would appreciate some help in creating
a R script to do this with minimal manual input. s A1-G1 and A2-G2 are

starting values update
...ies is created
by diluting it 1/3. i am reposting the full Absorbance data once again to
have a full idea about the output file created by the ELISA software. I am
also uploading the sample file for a better understanding, serum samples in
this case are diluted 4 times
