Hah - I guess I didn't mean I understood it in full as I expect I will
run into it again without anticipating it.
But, now that I know the "old adage" I will look there first when I
run into a problem.
Also, I used the square root of machine precision instead - thanks for
that, too.
Thank you, t

Well then you're doing much better than the rest of us: it's quite a
difficult subject and only gets trickier as you think about it more.

AHHH I GOT IT!!
And I *think* I understand about floating point arithmetic..
In this case vn$PM.DIST.TOT is the sum of proportions. So, it should
be anywhere 0 and 1.
In our case, if it's anything other than 1 when vn$PM.EXP is greater
than 0 then it means something is wrong wi
I see that you got other responses while I was composing an answer.
Your 'example.csv' did come through for me, but I still can't
replicate your PM.DIST_flag variable. Specifically, observations
30, 33, 36 and 40 are wrong.
I agree with Rui, that there's something else going on. The data

Hi Michael,
Thanks for letting me know how to post data. I will try to upload it
that way in a second.
I can usually use code to make a reproducible dataset but this time
with the ifelse behaving strangely (perhaps, it's probably me) I
didn't think I could do it easily so I figured I would just
Oh, sorry, I first though you couldn't post data to the list, but then
I thought I remembered other people doing so, so I tried to post it.
Here is a copy.
Thanks,

Hi Michael,
No, I never use attach(), exactly for the reasons you state. To do
due diligence I did a search of code for the function and it didn't
come up (I would have been shocked because I never us it!).
Now that real data is up, does your suggestion still apply? I am
reading it now.
Thanks
Off the wall / wild guess, do you use attach() frequently? Not
entirely sure how it would come up, but it tends to make weird errors
like this occur.

Hi Rui,
Thanks so much for responding but I think with my HTML problem the vn
data you made must not be the same. I tried running your code on the
data (I uploaded a copy) and I got the same thing I had before.

Hello,
Michael's standard guess, FAQ 7.31, was also mine, but is wrong. The
error is in Jennifer's flag column, not the result of her ifelse. (!)

Hi Peter,
I'm really sorry, I thought I was in plain text. I don't use any
formatting in my emails and in Gmail the HTML looks the same as plain
text.
Anyway, I've attached the data (I didn't think we could do that but I
am frequently wrong).
I say many cases because this is just a subset of >3
Bert,
I will thank you not to condescend to me, as I am too damn old (40) to
be treated that way. You didn't even offer a solution to my problem.
You only came to chastise me with regards to your assumptions about
me, which is very annoying.
While I am at the beginner level of R, I am not an idi

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$PM.DIST.TOT != 1.0), 1,
0 )
And here is my output that doesn't make ANY
To check for NA, use is.na. For instance your second ifelse should read:
ifelse(is.na(Sheet1$Claims),0,Sheet1$Claims))
Converting Sheet1$Claims to character doesn't have the effect you
think it does. NA is still NA, it does not become "NA". Try for
instance:
as.character(NA)
as.character(NA)
Could someone help me with the following code snippet. The results are not
what I expect:
> Sheet1$Claims[1:10]
[1] NA 1 2 NA NA NA NA NA NA NA
> Sheet1[1:10,"SubmissionStatus"]
[1] Declined Bound Bound Bound Bound Bound Declined
Dead Declined
