[R] Reading Data

[arun]

Hi,

I tried to read your data from the image:
OPENCUT<- read.table("OpenCut.dat",header=TRUE,sep="\t")

str(OPENCUT)

Not sure how you got that errors.  It would be better if you dput(OPENCUT).

Hi, 

I know there are several similar post, but I really have troubles reading a simple .dat file and I don't understand why. 
In fact, I am being able to import the data but only the first and last column are recognized as a proper vector set. 
Could you please tell me why I am not being able to read SR and LC columns??? Please see the screenshot attached: 

  

As you can see, columns FC and DM are well read by R however the
 other two are not. I've also tried to import it as a csv sheet but the 
result was the same. 

Any help would be appreciated! 

Many thanks, 

Stoyan
