Re: [R] adding labels to x,y points
A sample data would help. But you could modify as
text(x,y, label = row.names(colon[1:20,]))

[R] adding labels to x,y points
Hi,
I am new to R.
I have a matrix that I have assigned to the object “colon”.
> colon<-read.table("c:\\alon.txt",header=T,row.names=1)
attach(colon)
names(colon)
The dimenstions are 2000 62.
Each of the 62 columns (titled norm1, norm2, norm3, etc) has 2000
different numbers (‘continuous’ values) within it.
I have also assigned a name for each of the 2000 rows of the dataframe with
a prefix (i.e. g1 …. g2000) using the code (not sure if I did this right):
> colon<-paste("g",c(1:nrow(colon)),sep="")
I have plotted the first 20 values from two of the columns(samples).
> x<-c(norm1[1:20])
> y<-c(norm2[1:20])
> plot(x,y,type='n',xlab='x norm1 sample',ylab='y norm2 sample',main='Norm1
> vs Norm2 - 20
genes')
> points(x,y,pch=15,col='blue')
Now I wish to assign labels to each point (above each point (i.e. pos=3) in
the plot with “g1 to g20 corresponding to each row but I am having trouble
with this step.
I have tried:
> text(x,y, label = row.names(colon[1:20]))
but nothing happens.
Any suggestions?
Thanks in advance
MAB

Re: [R] adding labels to x,y points
Actually, you appear to have re-assigned your object “colon” (from
"c:\\alon.txt") with a character vector of intended row.names.
so use
row.names(colon) <-paste("g",c(1:nrow(colon)),sep="")

Re: [R] adding labels to x,y points
I don't have access to your "alon.txt" file (see ?dput for future posts),
but...
I'm pretty sure info you want isn't in row.names(colon[1:2])
it should just be
text(x,y, label = colon[1:20])
??
