I'm trying to wean myself off the very limited capabilities of Excel and Oo. Currently, I am trying to make a plot showing several values for 2 categories in a dot blot (see http://www.nabble.com/file/p24538360/Picture%2B1.png Picture+1.png except that the x axis should contain the category not a number, which was the only way to coax Excel into displaying a plot like this). I started working through some tutorials but the example didn't quite fit what I was looking for. The closest was the car and mpg example but it 1 value per name whereas I need several value per category. Does anybody know this of the top of your expert heads? This would be a great help. I already burned a few hours without getting closer to the solution..

The you could do like this: x1 = rep(1,times=length(y1)) x2 = rep(2,times=length(y2)) plot(c(x1,x2),c(y1,y2),xaxt="n") axis(side=1,at=c(1,2),labels=c("label1","label2")) It looks like a hack, but it should work. -- Michael Knudsen micknudsen at gmail.com http://lifeofknudsen.blogspot.com/

I use the long way, you might have to play around with my script to get is
correct. once you get it to work, you can add as many points to reflect,
median, percentile etc.
## generatiing vectors for Group1
a<-LMMP8[Self_T1D=="N"]
w <- a[!is.na(a)]
length(w)
c<-mean(a, na.rm=TRUE)
c
n<-as.integer(length(w)/7)
n
n4<- length(w)-6*n
n4
###Generating vectors for T1D
b<-LMMP8[Self_T1D=="Y"]
x <- b[!is.na(b)]
length(x)
d<-mean (b, na.rm=TRUE)
d
m<-as.integer(length(x)/7)
m
m4<- length(x)-6*m
m4
u<-append(w, x, after = length(w))
length(u)
x<-c(rep(1:6,n),rep(7,n4), rep(11:16,m),rep(17,m4))
length(x)
#####Plotting the data
plot(x,u, ylab="Log MMP8",pch=19,cex.lab=1.5,lty=2,cex=1.1,
cex.axis=1.25,xaxt="n")
points(4,c,pch=25,col="red",lwd=5)
points(14,d,pch=25,col="red",lwd=5)
