I have a text file like this
2.5 3.6 7.1 7.9
100 3 4 2 3
200 3.1 4 3 3
300 2.2 3.3 2 4
I used "r <- read.table("a.txt", header=T)"
The row names becomes X2.5, X3.6... What I need is the row names are numeric, so I can use the row names as numbers on x-axis for plotting. e.g. "plot(colMeans(r)~names(r))", something like this. How to do this?
Thanks.

Hi,
Try this:
dat1<-read.table(text="
2.5 3.6 7.1 7.9
100 3 4 2 3
200 3.1 4 3 3
300 2.2 3.3 2 4
",sep="",header=TRUE)
#Either
colnames(dat1)<-c("2.5","3.6","7.1","7.9")
#or
colnames(dat1)<-c(2.5,3.6,7.1,7.9)
#produce character column names
is.character(colnames(dat1))
[1] TRUE
is.numeric(colnames(dat1))
[1] FALSE
dat1
2.5 3.6 7.1 7.9
100 3.0 4.0 2 3
200 3.1 4.0 3 3
300 2.2 3.3 2 4

just do this:
colnames(r)<-substr(colnames(r),2,nchar(colnames(r)))
This will remove the X.
Later when you want to use the headed to plot something, cast it as numeric:
plot(colMeans(r)~as.numeric(colnames(r)))

Thanks Yasir, this helps a lot.
BTW, is there an R command to read just the first line of the file?

Thanks, but I don't want to specify the column names by hand, since I have a lot of similar files.

Hello,
I saw your reply in nabble. Sorry about that. I thought the dataset had only few columns.
#You can read first line of a file using:
readLines("foo.txt",n=1)[1]
#The more generic colname substitution
dat1<-read.table(text="
2.5 3.6 7.1 7.9
100 3 4 2 3
200 3.1 4 3 3
300 2.2 3.3 2 4
",sep="",header=TRUE)
#The code should remove the "X" from the column names (row names?)
colnames(dat1)<-gsub("^[X](.*)","\\1",colnames(dat1))
dat1
2.5 3.6 7.1 7.9
100 3.0 4.0 2 3
200 3.1 4.0 3 3
300 2.2 3.3 2 4
plot(colMeans(dat1)~as.numeric(names(dat1)),xlab="Column_Name",ylab="Column_Mean")

scan() or readLines() will read as many lines of the file as you want.
Use the file() function to open a "file connection" so a subsequent
read.table() will start where scan() or readLines() finished. E.g.,
> tfile <- tempfile()
> cat(file=tfile, " 2.5 3.6 7.1 7.9
+ 100 3 4 2 3
+ 200 3.1 4 3 3
+ 300 2.2 3.3 2 4
+ ") # now tfile looks like your example file
> read.table(header=TRUE, tfile) # easy way, but not what you want
X2.5 X3.6 X7.1 X7.9
100 3.0 4.0 2 3
200 3.1 4.0 3 3
300 2.2 3.3 2 4
> fileConn <- file(tfile, open="r")
> scan(fileConn, what=0.0, nlines=1)

Hi Peter,
I copied the data from your email and run it again.
dat1<-read.table(text="
2.5 3.6 7.1 7.9
100 3 4 2 3
200 3.1 4 3 3

dat1

100 3.0 4.0 2 3
200 3.1 4.0 3 3
300 2.2 3.3 2 4
colnames(dat1)<-gsub("^[X](.*)","\\1",colnames(dat1))
I am not sure what happened with your end. May be you could try
readtable(...., fill=TRUE)
I guess Chi was able to read it as I understood from his email:
("Thanks. It works very good.Chi"

The clue seems to be that the 3rd variant has a trailing space added to each line. No big deal, just drove me up the wall for while this afternoon...

>>
>> I have a text file like this
>> 2.5 3.6 7.1 7.9
>> 100 3 4 2 3
>> 200 3.1 4 3 3
>> 300 2.2 3.3 2 4
>>
>> I used "r <- read.table("a.txt", header=T)"
>> The row names becomes X2.5, X3.6... What I need is the row names are
>> numeric, so I can use the row names as numbers on x-axis for plotting. e.g.
>> "plot(colMeans(r)~names(r))", something like this. How to do this?
>>
>> Thanks.
