Re: [R] dataframe subsetting

[Spencer Graves]

Can you cut the data.frame down to just 2 rows and 2 columns that 
display the error?  You might find the error in the process of doing 
that.  If not, you should be able to distribute your same question with 
an example so anyone else can reproduce the problem.

This doesn't answer your question, but this technique can be used to 
resolve many difficult problems.

I can create a small dataset, "x" below, and subset out rows based on 
values of a certain variable.  However, on the dataset I'm working on now, 
"latdata" below, I get a subscript error.  Any advice is appreciated!

Successful:


is.data.frame(x)
[1] TRUE

x
  X1 X2 X3
1  1  3  5
2  2  4  6
x[x$X2 %in% c(3),]
  X1 X2 X3
1  1  3  5
Unsuccessful:


is.data.frame(latdata)
[1] TRUE

is.numeric(latdata$intent)
[1] TRUE

table(latdata$intent)


  1   2   3   4   5   6 
 34  23  67 179 996   2 

unlikely <- latdata[latdata$intent %in% c(1,2,3,4),]
Error in x[[j]] : subscript out of bounds
