try the code below,
if you use different upper and lower limits you might get different parameter
estimates
HTH, Victor
standard.curve<-data.frame(conc=c(50, 25, 12.5, 6.25, 3.125, 1.563, 0.781,50,
25, 12.5, 6.25, 3.125, 1.563, 0.781),absorb=c(1.918, 1.251, 1.104, 0.719,
0.403, 0.177, 0.083,1.9
another option is to use reshape()
x<-data.frame(x1=rep(1:3,each=3),x2=letters[1:9])
x$id<-rep(1:3,3)
dur<-reshape(x,timevar="x1",idvar="id",direction="wide")
dur<-dur[,-1]
colnames(dur) <- paste("d", unique(x$x1), sep="")
dur
cheers, Victor

although the code somehow didn't work on my Vista / R 2.8,
it did work perfectly on a XP machine / R 2.10
I've been trying to fix this for days,
Thank you very much for your help!

I guess you should specify x and y variables:
plot(x=PCECTPI$var1, y=PCECTPI$var2, axes = FALSE)

PLEASE do read the posting guide http://www.R-project.org/posting-gui
Please, I wonder if someone knows how to add the
less than or equal to symbol in the plot generated by the code below:
var1<-c('age <= 3','age <= 7','age <= 10','age <= 11','age <= 20','age <=
25','age <= 30','age <= 45','age <= 50','age < 55','age >= 55')
var2<-c(3.8,5.4,3.7,3.8,5.

lish what end? You have not described what you are trying to
actually do. Is this text supposed to be plotted inside the plotting
area or are you going to be using it as axis labels? There is a
variety of approaches (especially the plotmath expression option) that
can be used depending on the ultim
Dear all,
Please, I have a doubt regarding symbols plotting
when the data originates from a table
(i.e. is not manually fed into the "text" function)
Please, see below:
I have a tab delimited file called table1.txt with 4 columns.
(I wasn't sure on how to attach the table to t
"bill >= tony" "bill \u2265 tony"
"9" "fish" "dude <= bro" "dude \u2264 bro"
By the way, I'm running R on windows and didn't try any of this on Linux.
thanks in advance, Victor
