Histogram with uneven bins
Hi R-helpers
I would like to produce a histogram with uneven bins (e.g., 0, 1-2, 3-5,
6-10, 10-20, >20) but I would like the resulting bars to be the same width (
i.e., a bar's width would not be proportional to its corresponding bin
size).
Also, the x and y axes of my histograms frequently (almost always, actually)
extend beyond the axis labels (i.e., there are unlabeled bars). I would

Using minsplit and unequal weights in rpart
Dear r-help mailing list,
Is there a way to incorporate weights into the minsplit criteria in rpart,
when the weights are uneven? I could not find a way for the minsplit
threshold to take the weights into account, and when the weights are uneven
it becomes an issue, as the following example shows.
My current workaround is to expand the data into one in which each row is
an observation, but that

Averaging uneven measurements by time with uneven numbers of measurements
I have a new device that takes measurements anywhere from every second, to
every 15 minutes (depending on changes). The matrix has a date, time and Y
column (Y is the measurement). For three days it is 25,000 rows. How do I
average the measurements by every 30 minutes so my matrix is 48 rows per
day? I have been working on this and cannot figure out a simple method. Any
ideas? Thank you.

X-Axis Problem with Multhist Plot
I am creating a side-by-side histogram using "multhist" of PLOTRIX.
However, I can't seem to control the X-axis.
It yields the following X points in the axis:
1 3 5 7 9 13 17 21 25 29 33
with uneven spacing between x-ticks (see attached file).
Especially I want to create a bar for every x-axis (1,2,3,4...36),
now not every x-axis has a bar.
Is there a way to alter my following

Count of Histogram Bins using Shingles with lattice
I know that I can get a count of histogram bins in base R with plot=FALSE. However, I'd like to do the same thing with lattice. The problem is that I've set up shingles, and I'd like to get the count within each bin within each shingle. plot=FALSE doesn't seem to do it.

String manipulation, insert delim
Hello All,
I've been using R for two years now and I am happy to say this is the
first time I could not find the answer to my problem in the R-help
archives. Here is the pending problem:
I want to be able to insert delimiters, say commas, into a string of
characters at uneven intervals such that:
foo<-c("haveaniceday")#my string of character
bar<-c(4,1,4,3) # my vector of

how to fill out the empty spots when using rbind or cbind?
I have uneven vectors I want to use cbind or rbind to combine them into a matrix. Is there a way to make it so that R would not return error msg saying they're uneven?
Thanks.

Histogram from frequency data in pre-made bins
Dear R user,
I am using UK census data on travel to work. The authorities have provided a
breakdown in each area by mode (car, bicycle etc.) and distance travelled (0
? 2 km, 2 ? 5 km etc). Therefore, after processing, the data for Sheffield
look like this https://files.one.ubuntu.com/ej2VtVbJTEaelvMRlsocRg :

uneven vector length issue with read.zoo?

plot, y-axis, uneven scale???
Hello,
I have a question about the y-axis of plots. Actually I had about 60
values. About 80 percent of these values are less than 0.2, then the other
20 percent values are more than 4,max is 10. So when I plot these values
together, the y-axis's range will go 0 to 10, and my major values (80%
values <0.2) will be pressed around 0 on the bottom, while other several
dots will scatter in

Breaks in y-axis of histogram using lattice
Hello R-Users,
I am plotting several histograms to demonstrate zero-inflated data using
lattice. Because there are so many zeros, it is difficult to see the
observations of non-zeros on the graph (i.e. the y-axis scale is too
large). I would like to break the y-scale so that the non-zeros at
least show up on the graph. Below is an example of the code for the
histogram (e.g. I have several

Help with R graphics
I need to make a plot illustrating main characterisitig of river
drainage data. For this I have 2 questions:
how can I rotate a histogram -90? (or 270?) (like the horizontal=TRUE

how can I use split.screen to produce 3 plot with uneuqal size (1/5,
2/5, 2/5 of the screen width)?

Generating a vector for breaks in a histogram
Hi
I have two lots of numbers which I would like to histogram using the hist() function. For comparative reasons, I want them to be on the same scale, which I can use the xlim and ylim options to achieve.
However, having them on the same scale is meaningless unless they have the same "breaks". Consulting the documentation, there are 4 ways of defining the number of breaks, only one

Drawing asymmetric error bars

I have data which I have arcsin transformed to analyse.
I want to plot my data with error bars however as my data is
back-transformed my standard errors are uneven.
Is there a simple way to draw these asymmetric error bars in R?

Odd behavior in histogram breaks?
I am looking at histogram breaks, and notice something odd:
> foo <- hist(runif(10000),breaks=20)
> length(foo$breaks)
[1] 21
This makes sense to me.
> foo <- hist(runif(10000),breaks=200)
> length(foo$breaks)
[1] 201
This also makes sense.
BUT
> foo <- hist(runif(10000),breaks=250)
> length(foo$breaks)
[1] 201
> foo <- hist(runif(100000),breaks=250)

Histogram not plotting correct breaks
Hi,
I'm using the hist function to plot the frequency of 21 variables, but it
keeps starting the x-axis from 0 and adding variables 1 and 2 together (all
other vairables have the correct frequencies). I suspect it adds 1 and 2
together so that 0 can fit in with demarcations at intervals of 5. Using
"xlim=c(1,21)" to specify that i don't want to include 0 and using the
