problem post request with RCurl
Hi, I am trying to use a CGI service (Pubchem PUG) via RCurl and am
running into a problem where the data must be supplied via POST - but
I don't know the keyword for the argument.
The data to be sent is an XML fragment. I can do this via the command
line using curl: I save the XML string to a file called query.xml and
then do
curl -d @query.xml

Are you sure? I'm seeing here:

This doesn't make any sense to me, either. There can't be more packages
transmitted than received. It's the same codec in and out and it's been
running exactly the same time.

Could this gap in sequence numbers caused by a codec change generate
errors like the one below?

for loop
Hello,
I have a simple question: I want to list numbers 1:k, but if k <1, I hope nothing listed.
how should we do?
k=2
for (i in 1:k) print(i)
[1] 1 # <-correct
[1] 2
k=0
for (i in 1:k) print(i)
[1] 1 #<---- wrong
[1] 0
thanks

Create new data frame with conditional sums
Under the hood, sapply() is also a loop (at the interpreted level). As
is lapply(), etc.

Create new data frame with conditional sums
Well, here's one way to do it:
(dat is your example data frame)
Cutoff <- seq(0, .15, .01)
Pop <- with(dat, sapply(Cutoff, \(p)sum(Totpop[Pct >= p])))
I think there must be a more efficient way to do it with cumsum(), though.
Cheers,

Applying function to only numeric variable (plyr package?)
My data frame consists of character variables, factors, and proportions,
something like
c1 <- c("A", "B", "C", "C")
c2 <- factor(c(1, 1, 2, 2), labels = c("Y","N"))
x <- c(0.5234, 0.6919, 0.2307, 0.1160)
y <- c(0.9251, 0.7616, 0.3624, 0.4462)

read big text file into R
Dear Rs:
Hi, I am trying to read a big text file (nrows=243440, ncols=144). It
seems the computational time of all the read methods
(scan,readtable,read.delim) is not linear to the number of rows I
want to read in: things became really slow once I tried to read in
100000 lines compare to 10000 lines).
If I am reading the profiling result right, I guess scan wouldn't
help either.

profiler and loops
Hello,
(This is follow up from this thread:
http://www.nabble.com/execution-time-of-.packages-td22304833.html but
with a different focus)
I am often confused by the result of the profiler, when a loop is
involved. Consider these two scripts:
script1:
Rprof( )
x <- numeric( )
for( i in 1:10000){
x <- c( x, rnorm(10) )
}
Rprof( NULL )
print( summaryRprof( ) )

More simple implementation is slow.
Hi all.
I'm developing a function, which must return a square matrix.
Here is the code:
http://pastebin.com/THzEW9N7
These functions implement an analog of two embedded for cycles.
The first variant creates the resulting matrix by columns, cbind()-ing them
one by one.
The second variant creates the matrix with two columns, which rows contain
all possible
variants of i and j and calls apply

Create new data frame with conditional sums
If one makes the reasonable assumption that Pct is much larger than
Cutoff, sorting Cutoff is the expensive part e.g O(nlog2(n) for
Quicksort (n = length Cutoff). I believe looping is O(n^2). Jeff's
approach using findInterval may be faster. Of course implementation
details matter.

Summary model with observations taken out and dummied back in - not working
I have a data set with 35 observations and 4 variables. I have removed 4
observations as they were skewing the data analysis but I want to dummy them
back in, (not entirely sure on the reason, but have been told I should try).
I have used this in order to do it, but I am not getting any statistical
analysis with my dummy it's all NA.
