R help - Oct 2012 - barplot

Hi,

I want to make a barplot with the following datasets:

I have a file as following:

name  chr position A1 A2 pop1 pop1 pop2 pop2

I have calculated a measure using all the values in columns "pops",
the
values are saved in a vector.

Now I want to make a barplot using the values in this vector as the y axis
and the values in the column "position" in the x-axis.

thank you for your help.

Hi,

May be this example helps you.
dat1<-data.frame(position=
1:5,pop1=c(3,5,15,25,28),pop2=c(5,8,12,22,35),pop3=c(2,10,17,20,31))
dat2<-melt(dat1,id.vars="position")
library(lattice)
barchart(value~factor(position),data=dat2)
A.K.

Hi Thiho,
You can do this with the "barp" function in the plotrix package. See
the
"x" argument for placing the bars at arbitrary positions.
