Basic question about re-writing for loop as a function
...he function to return, for the first column,
1, 1, 1, 1, 0, 0, 1, 1, 0, 0 (because those are the values of Words
which contain a 1) and for the second column return 0, 0, 0, 0, 1, 0,
0, 0, 0, 0 (because the fifth value is the only one that contains a
2).
Any suggestions gratefully received!

Some coefficients are doubled when I use the step() function
...plicated as "S1Q7.11" and "S1Q7.12" etc.
I've googled and read and re-read the step() and stepAIC()
documentation and I just can't figure out what it could mean. Removing
the test="F" bit also generates the same behaviour.
Any help greatly appreciated.

Subset command and the : operator
...ing error message:
In X2 == 9:12 :
longer object length is not a multiple of shorter object length
I know I can use X1[ Time < 9 & Time > 3] but I would like to know
what is wrong with the 5:8 usage in case I put it somewhere else and
don't notice the problem.
Many thanks!

Match strings across two differently sized dataframes and copy corresponding row to dataframe
...(mydata$ImproveCat1[datavec[!is.na(datavec)]]) # yields 1567
length(comments$ImproveCat[commvec[!is.na(commvec)]]) # yields 1512
I'm sorry, I did try to construct an example dataframe, but ironically
I can't make that work either! Sorry!
Any help gratefully received.
Many thanks!

Replace selected columns of a dataframe with NA
...ould be much more important, if say I just wanted to
replace the odd columns, or something like that.
I found this code on the internet too:
idx <- which(foo>80, arr.ind=TRUE)
foo[idx[1], idx[2]] <- NA
But I can't seem to rewrite that either, for the same reason
Many thanks!

How to remove rows based on frequency of factor and then difference date scores
...starts at Date "1" and goes up in integers according to how
many days have elapsed.
I just know there's some incredibly cunning R-ish way of doing this
but after many hours of fiddling I have had to admit defeat.
I would be very grateful for any words of advice.
Many thanks,

Nested brew call yields Error in .brew.cat(26, 28) : unused argument(s) (26, 28)
...likely that I need to insert into the script
the actual content of .brew.cat, but I can't seem to get R to tell me
what it is and Googling throws up a lot of stuff about beer and not much
else (drew a blank also from RSiteSearch("Nested brew"))
Any help gratefully received.

odfWeave repeats output
...t sure which version I'm
afraid). I've been unable to find anyone on any forums or anything
with the same problem.
Using R v2.13 on Windows, v 2.12 on Linux, was using RStudio but just
tested it without (just in case) and it does the same thing.
Any suggestions gratefully received.

as.numeric() generates NAs inside an apply call, but fine outside of it
...bout the apply
call that generates the NAs when as.numeric(mydata[,2]) doesn't and I'm
not sure what to do about it in future.
I realise I can just loop over the columns, but I would rather get to
the bottom of this if I can so I know for future.
Thanks in advance for any advice

anova of lme objects (model1, model2) gives different results depending on order of models
...8926 <.0001
In both cases I am led to accept model 2 even though they are opposite
models. Is it really just that you have to put them in the right order?
It just seems like if there were say four models you wouldn't
necessarily be able to determine the correct order.
Many thanks,

Problem with aggregating data across time points
...ly I still want these dates to appear- so
e.g. 21-5-2008 would appear as 0 0 0 0, then 22-5-2008 might have 1 2
0 0, then 23-5-2008 0 0 0 0 again, and etc.
I've had several abortive attempts and done some Googling but have got
nowhere. I'd greatly appreciate any advice.
Many thanks,
