Change the default resolution for plotting figures?
Hi,
I want to save a plot in the windows device as png and the default
resolution is 72dpi. Is it possible to increase the default resolution
to for example 300 dpi?
I have thought of using function png(..., res=300), but the problem is
that the figure produced this way looks different than the one shown
in the windows device. One notable difference is the missing of some
ticks in the x

How to determine a subset of a binary strings?
Hi,
I need some neat ways of determing a subset of binary strings. For example,
x=c(0,0,1), y=c(0,1,1), z=c(0,1,0). So x is a subset of y and z is also a
subset of y, but x is not a subset of z.
I tried to search R functions and packages but no hits. Any ideas?
Best,
Jing

download.file error
Dear all,
I am looking for a way to work out if a file on the internet exists before attempting to download it using the function download.file(). For example,
using a url that does not exist
url <- "http://finance.yahoo.com/ftse.csv"
destfile <- tempfile()
download.file(url = url, destfile = destfile)

Calculation of e^{z^2/2} for a normal deviate z
I agree with many the sentiments about the wisdom of computing very
small p-values (although the example below may win some kind of a prize:
I've seen people talking about p-values of the order of 10^(-2000), but
never 10^(-(10^8)) !). That said, there are a several tricks for
getting more reasonable sums of very small probabilities. The first is
to scale the p-values by dividing the

Error in inherits(x, "data.frame") : subscript out of bounds
Hi,
I have a list p with different size dataframes and length of over
8000. I'm trying to
calculate correlations between the rows of dataframes of this list and
columns of another
dataset (type data.frame also) so that first column is correlated with
all the rows in
the list dataframe. Some information from another dataset is also
included to the final
output (all.corrs). This worked a

Calculation of e^{z^2/2} for a normal deviate z
You may want to look into using the log option to qnorm
e.g., in round figures:
> log(1e-300)
[1] -690.7755
> qnorm(-691, log=TRUE)
[1] -37.05315
> exp(37^2/2)
[1] 1.881797e+297
> exp(-37^2/2)
[1] 5.314068e-298
Notice that floating point representation cuts out at 1e+/-308 or so. If you want to go outside that range, you may need explicit manipulation of the log values. qnorm()

R-package "FunctSNP"
Hy everyone,
I am new in R so I will pose a simple question that I cannot find out
reading tutorials.
I would like to install the R-package "FunctSNP" by file.zip because
it?s in the archive
(http://ftp.sunet.se/pub/lang/CRAN/src/contrib/Archive/FunctSNP/)
but It doesn?t work, I think some problem concernings library.
Could someone show me how to do?
Thanks

changing 'https' to 'http' when using download.file(), any side effects or just use RCurl?

use of buffers in sprintf and snprintf
Hi again,
I realised it is useful to replicate the warnings locally without relying on CRAN automatic check; instead of R(-devel) CMD check --as-cran package_version.tar.gz one can use
R CMD check --configure-args=""
and in my case the WARNINGS were initially given with https://www.stats.ox.ac.uk/pub/bdr/gcc9/README.txt and those specification might as well used in --configure-args

download.file
I am downloading say 100 files from ucsc website and storing it into dest
folder.
download.file function create a file in destination folder even if the file
is not present which is something I dont want.
So I wrote if condition to remove the file if the download function has non
zero value.
Now it exits when there is an error or file not present. How can I use

problem for wtd.quantile()
Dear R-users,
I don't know if there is a problem in wtd.quantile (from library "Hmisc"):
--------------------------------
x <- c(1,2,3,4,5)
w <- c(0.5,0.4,0.3,0.2,0.1)
wtd.quantile(x,weights=w)
-------------------------------
The output is:
0% 25% 50% 75% 100%
3.00 3.25 3.50 3.75 4.00
The version of R I am using is: 2.1.0
