Preparing high quality figures with tiff as end result
Hi all,
I'm currently preparing some figures that will be submitted to PloS One.
In their guidelines they state that they will only accept figures in
tiff or eps format, with the warning that eps figures will be
converted to tiff format ( see
http://www.plosone.org/static/figureGuidelines.action ).
Because of this conversion, I figured I'd generate tiff-format figures
from the beginning.

download.file not working
Hi all,
I'm trying to download a file from the net, and the download.file
command leaves it corrupted, i.e excel cannot open it. It seems as if
it's going ok, however.
Does anyone have an idea of what's going on?
regards,
Gustaf Rydevik

The "$" operator and vectors
Hi all,
I've run into a slightly illogical (to me) behaviour with the "$"
subsetting function.
consider:
> Test
A B
1 1 Q
2 2 R
> Test$A
[1] 1 2
> vector<-"A"
> Test$vector
NULL
> Test$"A"
[1] 1 2
> Test[,vector]
[1] 1 2
Is there a reason for the $ operator not evaluating the vector before executing?
best,
Gustaf

two-sample test of multinomial proportion
Hi all,
This is perhaps more a statistics question than an R question, but I
hope it's OK anyhow.
I have some data (see below) with the number of tests positive to
subtype H1 of a virus, the number of tests postive to subtype H3, and
the total number of tests. This is for two different groups, and the
two subtypes are mutually exclusive.
What is the best way to test if the proportion of H1

"utils" lacking namespace?
Hi all,
A colleague of mine tried to install the package EMV, which had been
removed from CRAN.
she ran into some kind of trouble, R locked up, and she closed the program.
Now when she starts R, "utils" can't be loaded which of course create
an unworkable environment.
Below I've copy-pasted the error message she gets when starting R.
Any ideas on what went wrong, and more

Aggregate?
Hi All,
I think i'm failing to undersatnd how aggregate() is supposed to work.
example:
test1<-sample(c(0,1),100,replace=T)
test2<-sample(letters,100,replace=T)
aggregate(test1,list(test2),sum)
Error in data.frame(w, lapply(y, unlist, use.names = FALSE)) :
arguments imply differing number of rows: 26, 0
I thought this would give me a list containing the number of ones that

WHO Anthro growth curve macros and R
Hi all,
I've got a project where I have to calculate weight-for-age Z-scores,
preferably using the WHO standards.
WHO have been very nice to publish macros for doing this in both
STATA,SPSS, SAS and Splus formats
(see http://www.who.int/childgrowth/software/en/), but for some reason
have chosen not to use the free R alternative to Splus.
In the Splus zipfile there are nine datafiles with a

A revised function for getting ISO week
Hi All,
Two years back, I posted a small function for getting the ISO 8601
defined week number of a date (such as the week number used in all
Swedish calendars),
in a os-independent manner.
I've since discovered an inaccuracy in that code, and so I thought I'd
repost the corrected version.
Hopefully this will come in handy for someone searching the mailing
list archives in the future.

Plot to tiff, font size problem in multiple plot figures
I am creating graphs for a publication and would like them to have the same
font size... but when I create a figure with multiple plots, the font size
decreases even though I haven't changed the tiff() resolution or
pointsize specifications, I have increased the figure size according to how
many plots it will ultimately have, and I have made sure the margins are
equivalent for single and

Change the position of panel strips in a lattice plot.
Hi all,
In lattice plots, is there any option to position the panel strips
with text below each subgraph, instead of above?
i.e. in:
Depth <- equal.count(quakes$depth, number=8, overlap=.1)
xyplot(lat ~ long | Depth, data = quakes)
,is there any way to make "Depth" appear below the subgraphs, instead of above?
I've been looking through the lattice documentation and the list

Vertical line in densityplot?
Hi all,
I'm trying to get a vertical line at a specific point in a
densityplot. abline seems to be what's required, but it doesn't align
itself to the scale used in the plot.
example:
library(lattice)
x<-rnorm(100)
plot.new()
densityplot(x)
abline(v=0)

The line seems to use some other coordinate system. What kind of call
do I use to make abline use the graph's

reshape, direction=long: "multiple row names not allowed"
Hi all,
for some reason I always get stuck spending hours when trying to use
reshape or the Reshape package. Heaven knows why.
My latest frustration (in 2.7.1, so ignore if this has been fixed):
test<-data.frame(matrix(rnorm(42*4),ncol=4),rep(1:21,2),rep(c("a","b"),each=21))
reshape(test,varying=list(colnames(test)[1:4]),direction="long")

x-axis order
Hi all,
I have a time series which contain data collected weekly from week 26
to week 25 the following year. How do I plot this data, so that the
x-axis is displaying the week numbers, ordered as in the data?
Thanks in advance,

moving average on irregular time series
Hi all,
I wonder if there is any way to calculate a moving average on an
irregular time series, or use the rollapply function in zoo?
I have a set of dates where I want to check if there has been an event
14 days prior to each time point in order to mark these timepoints for
removal, and can't figure out a good way to do it.
Many thanks in advance!

Avoiding overplotting of text.
Hi all,
I am plotting some data, and use text() to get variable names next to
points on the graph. What is the best way to make sure that these text
labels are readable and not overlapping when two datapoints are close?
I've tried using jitter(), but the effect is random and doesn't always
give a good result.
Any suggestions would be most appreciated.
Best regards,
Gustaf
