Hello R Programmers!
I was wondering if y'all could help me. I'm trying to read data from a
directory containing 332 compressed zips all with about 1000 lines (or
more) of data into a data frame. I have it so that the directory is set to
the file with the zips in it. I figured this way when I tried
Hi R user,
I wanted to change a column name with new one but it comes with "." where
there was space. Is there any way to keep my formate with space?
Here what I found
Images<-stack(imageA,imageB,imageC)
names(Images)[3]<-c("dif of AB")
head(Images)
It gives the column name of 3 as a "dif.of.
I have seen less sensical questions.
It would be nice if the example were a bit more complete (as in it should have
excess degrees of freedom and an answer) and less like a homework problem
(which are off topic here). It would of course also be helpful if the OP were
to conform to the Posting G

You could try the following (I haven't tested it so check that the
results make sense):
indicator
I have 4-dimension array x(lat,lon,time,var)
I am using "apply" to calculate over time
new = apply(x,c(1,2,4),FUN=function(y) {length(which(y>=70))})

Adding the argument strip.white=TRUE to your call to read.csv() will remove
possible leading or trailing "white space" (spaces and tabs).

Dear R community,
I am a PhD student at the University of Münster writing my thesis in
psycholinguistics.
I am currently running statistical analysis on a dataset with 3 fixed
factors (syntax, position), each with 2 levels and their interaction
(syntax*position). The accuracy rate is the dependen

Just printing it will not tell you. I did not mean 'Have you spelled it
correctly?' I meant 'Is there a stray space somewhere?'. Peter has the
same suspicion.

Shivi;
See what this returns:
"honors" %in% levels(m11$prog)
The level is probably something like " honors"
It's fairly easy to inadvertently create leading or trailing spaces when
reading from comma-separa

Are you sure that the level is "honors" and not " honors" or "honors "
or something similar?
