rle() fails with NA's (PR#892)
Full_Name: Jeff Hallman
Version: 1.2.2
OS: Solaris
Submission from: (NULL) (132.200.32.33)
> rle(c(1, NA, 1)
$lengths
[1] 3
$values
[1] 1
should be as in Splus:
$lengths
[1] 1 1 1
$values
[1] 1 NA 1
The Splus implementation (which works fine in R) is:
rle <- function(x){
if(!is.atomic(x))
stop("Argument must have an atomic mode")
if(length(x) == 0)

how to use function of rle approx ifelse etc. in data frame
Hello R help,
I have this data frame M2[160000,5] with NAs, a simple example would be:
set.seed(1234)
M2<-expand.grid(ID=182:183, year=2012, month=1:3, day=1:3,
KEEP.OUT.ATTRS=FALSE)
M2 <- M2[with(M2, order(ID, year, month, day)),] #sort the data
M2$value <- sample(c(NA, rnorm(100)), nrow(M2),
prob=c(0.5, rep(0.5/100, 100)), replace=TRUE)
M2:

NAs and rle
Hi All,
A twitter user, Mike fc (@coolbutuseless) mentioned today that he was
surprised that repeated NAs weren't treated as a run by the rle function.
Now I know why they are not. NAs represent values which could be the same
or different from eachother if they were known, so from a purely conceptual
standpoint there is no way to tell whether they are the same and thus
constitute a run or

help with rle function on paired data
Dear R Community - I hope you might be able to provide some guidance
regarding the use of the rle function. I have a set of time-series data
where a measured value is recorded every 30 seconds after the start of an
experiment. Many of the measured values repeat and I am interested only in
the values when there is a change. If I turn the measured values into a
vector, the rle function works

Feed rle() output to hist()
I want to make a histogram from the lengths vector which is part of the
output of rle. But I don't know how to access that vector so that I use it
as an argument of hist(). What argument must I use so that I use the
lengths vector as an input to hist()?
Example output is:
Run Length Encoding
lengths: int [1:4] 1 2 3 3
values : num [1:4] -1 1 -1 1

rle on large data . . . without a for loop!
I think need to do something like this:
dat<-data.frame(state=sample(id=rep(1:5,each=200),1:3, 1000,
replace=T,prob=c(0.7,0.05,0.25)),V1=runif(1,10,1000),V2=rnorm(1000))
rle.dat<-rle(dat$state)
temp<-1
out<-data.frame(id=1:length(rle.dat$length))
for(i in 1:length(rle.dat$length)){
temp2<-temp+rle.dat$length[[i]]
out$V1[i]<-mean(dat$V1[temp:temp2])

ggplot2 Y axis labels
Hi all:
Using the example below, is there a way to add Y axis titles to each graphic instead of sharing the same title?
library(ggplot2)
RT = matrix(c(814, 500, 424, 394, 967, 574, 472, 446),4,2)
colnames(RT) = c('repetition','alternation')
rownames(RT) = c('7-yrs','11-yrs','15-yrs','21-yrs')

problem (and solution) to rle on vector with NA values
Hello there R-help,
I'm not sure if this should be posted here - so apologies if this is the case.
I've found a problem while using rle and am proposing a solution to the issue.
Description:
I ran into a niggle with rle today when working with vectors with NA values
(using R 2.31.0 on Windows 7 x64). It transpires that a run of NA values
is not encoded in the same way as a run of other

Duncan -
Indeed, this has now been well documented; I have called these constructions "Schr?dinger Facts", since they arise from a superposition of truths in the training data that collapse into an untruth when observed.

Now, the curious question is: why can it program. Why is its production of R-syntax less vulnerable

An interesting chat with ChatGPT
I was wondering which anchor would match in the regular expression
"(a)|(b)" if both "a" and "b" matches the target string. What appears
to happen is that the first match wins, and that's how it is documented
in Python, but I was looking for docs on this in R.
As far as I can see, the ?regex help page doesn't resolve this. So just
for fun, I decided to

Plotting problems directional or rose plots
Hi,
I'm trying to get a plot that looks somewhat like the attached image
(sketched in word).
I think I need somthing called a rose diagram? but I can't get it to do what
I want. I'm happy to use any library.
Essentially, I want a circle with degree slices every 10 degrees with 0 at
the top representing north, and
'tick marks' around the outside in 10 degree increments to
