[R] NULL column

[arun]

Hi Silvano,

You can save the data as "filename.txt" and then call read.table()
For example,

I saved your data:
#################################################
              beta0          beta1              pvalor        Crom
 rs17      158.5980 12.252462 9.083193e-135        1
 rs46      163.3730  3.304276  3.279925e-06          1
 rs63      162.7924  2.084678  5.023893e-06          1
 rs24      162.4252  1.837208  5.509042e-06          1
##################################################
as "dat11.txt"
dat1<-read.table("dat11.txt",sep="",header=TRUE)
dat2<-data.frame(new=rownames(dat1),dat1)
rownames(dat2)<-1:nrow(dat2)
dat2
   new    beta0     beta1        pvalor Crom
1 rs17 158.5980 12.252462 9.083193e-135    1
2 rs46 163.3730  3.304276  3.279925e-06    1
3 rs63 162.7924  2.084678  5.023893e-06    1
4 rs24 162.4252  1.837208  5.509042e-06    1

You can also save it as "filename.csv" and use read.csv() or read.delim() 
dat1<-read.csv("dat11.csv",sep="",header=TRUE)

Hope it helps.
A.K.

Hi Arun,

it worked perfectly.
The only problem is that the data set is great to put in the
read.table(text=" ")

But it worked.

Thank you
