[R] r bug (?) display of data

[Marc Jekel]

Hi R Fans,

I stumbled across a strange (I think) bug in R 2.9.1. I have read in a 
data file with 5934 rows and 9 columns with the commands:

daten = data.frame(read.table("C:/fussball.dat",header=TRUE))

Then I needed a subset of the data file:

newd = daten[daten[,1]!=daten[,2],]

--> two values do not meet the logical specification and are dropped.

The strange thing about it: When I print the newd in the R Console, the 
output still shows 5934 rows. When I check the number of rows with 
NROW(newd) , I get 5932 as output. When I print newd[5934, ], I get NAs. 
When I print newd[5932, ] I get the row that is listed in line 5934 when 
I just type in newd. This is totally crazy! Has anyone had the same 
problem? Thanks for a post.

Marc
