Hi R-Helpers,

I don't think I need to post a dataset for this question but if I do, I
can.  Anyway, I am having a lot of trouble with the ifelse command.

Here is my code:


vn$PM.DIST_flag <- ifelse( (vn$PM.EXP > 0.0) & (vn$PM.DIST.TOT != 1.0), 1,
0 )


And here is my output that doesn't make ANY sense:

  PM.EXP PM.DIST.TOT PM.DIST_flag  0 0 0  0 0 0  0 0 0  177502 1 0  31403 1
0  0 0 0  1100549 1 0  38762 1 0  0 0 0  20025 1 0  0 0 0  13742 1 0  0 0 0
83078 1 0  0 0 0  0 0 0  0 0 0  0 0 0  0 0 0  0 0 0  0 0 0  0 0 0  0 0 0
165114 1 0  0 0 0  417313 1 0  3546 1 0  4613 1 0  225460 1 0  6417 1 1  23
1 0  3402 1 0  8504 1 1  8552 1 0  9723 1 0  37273 1 1  396 1 0  1478 1 0
2074 1 0  12220 1 1  97691 2 1  0 0 0  33993 2 1

As you can see, there are many instances where PM.EXP > 0 and PM.DIST.TOT =
1 yet PM.DIST_flag = 1 and it should be 0.  It should only flag in cases
such as the last line of data.

WWHHHYYYYYYYY???? Why why why why why why why? Why?

(Sorry, I've been trying to figure this out for hours and I've devolved to
mumbling in corners and banging my head against the table)

What in the world am I doing wrong?  Or is ifelse not the right function?

Best,

Jen
