Are you sure? I'm seeing here:

of them are lost?! The Pct value is fluctuating between about 6009 and 9009.

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.

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
...hink that there's anything wrong with using a loop to solve
this problem, but it's generally a good idea to pre-allocate space for
the result rather than build it up one value at a time, which may cause
unnecessary copying of the object.
Here are three solutions:
f1 <- function(Cutoff, Pct, Totpop){
Pop <- numeric(0)
for (i in seq_along(Cutoff))
Pop[i] <- sum(Totpop[Pct >= Cutoff[i]])
cbind(Cutoff, Pop)
}

Pop <- numeric(length(Cutoff))

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?)
...tors, 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)
df <- data.frame(c1, c2, x, y)
pct <- function(x) round(100*x, 1)
I want to apply the pct function to only the numeric variables so that the
proportions are computed to percentages, and retain all the columns:
c1 c2 x1 x2
1 A Y 52.3 92.5
2 B Y 69.2 76.2
3 C N 23.1 36.2
4 C N 11.6 44.6

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.
