comma separated format
Hi All,
I'm trying to create labels to plot such that it doesn't show up as
scientific notation. So for example how do I get R to show 1e06 as
$1,000,000.
I was wondering if there was a single function which allows you to do that,
the same way that as.Date() allows you to show in date format on a plot.
Thanks,
Sachin

date conversion and plot
Hi All,
I have a date in the format of yymmdd (without any of the backslashes, eg.
100731). How do I convert this into a Rdate and plot it? I don't want the
number of days from 1970's showing up as my date (Its the date I require).
Thanks,
Sachin
p.s. sorry about the corporate notice I can't remove it.

parallel for loop
Hi all,
Just following on from a previous thread (for loop). Is there a parallel
'for' loop like matlab (parfor maybe?). I know there was a Nvidia GPU
version for blas somewhere. But is there a CPU or a GPU version of the for
loop?
Thanks,

arrays of arrays
Hi All,
I want to have an array/ matrix that looks this
x<- 0 0 1 1
1 3 5
4 4
7 -1 8 9 10 6
I hope this makes sense. So basically if I want x[1,3] it will access 0 and
similarly x[4,2], -1.
Thanks in advance,
Sachin

plot options including formatting axes
Hi All,
Currently my plot shows the y-axis in scientific notation (1e07 and so on).
I want to be able to display this in dollars such that it shows $10,000,000
(including the commas). How do I do this.
Also with the xlabel and ylabel. I've specified: 'title('Cash vs
Time',xlab='Period',ylab=''); Im hoping that this will also not display
anything on the y-axis.

drilling down data on charts
Hey all,
Suppose a=b^2 for starters. I want to be able to create a graph that
displays a initially and if i was to click on 'a' to show 'b' on the chart
itself. Does anyone know if this is possible in R?
Also as an extension (not necessary as yet) to output the above into a
'html' file.
Thanks,
Sachin

switching only axis off in plot
Hi R,
In the following code my x-axis is formatted in month format. Which Im
happy with. The y-axis is what I want to re-format with something else. My
question is, is it possible just to switch off the xaxis in plot function
(see below). If not how do you get the months to show up as FEB-YYYY,
MAR-YYYY and so on, so I could fit a label on x-axis.
Thanks,

Troubleshooting sweave
Hi All,
I've reproduced the example from Prof. Friedrich Leisch's webpage. When I
write sweave("Example-1.Snw") OR sweave("Example-1.Rnw"), (yes, I renamed
them). I get the following error:

Running R on a server
Hi All,
I am trying to run R scripts on a server rather than my own machine. The
biggest reason being that the data can be 3GB+; more than my RAM can
handle. Anyway is there a way to do this.
I am trying to find a SAS alternative.
In SAS you can do (keyword) rsubmit; and get things running remotely on a
server. Is there something similar on R. Couldn't find a comprehensive
answer online.

cannot see the y-labels (getting cut-off)
Hi All,
When I run the following code, I cannot see the entire number. As opposed
to seeing 1,000,000,000. I only see 000,000 because the rest is cut off.
The cex option doesn't seem to be doing anything at all.
y<-seq(1e09,5e09,1e09);
plot(1:5,y,ylab='',yaxt='n' );
axis(2, at=y, labels=formatC(y,big.mark=",",format="fg"),las=2,cex=0.1);
Any thoughts?

loading workspace- getting annoying
I stupidly decided to save my last workspace (a large dataset) and every
time I open R it loads it back in. Can I stop this? Also how do you clear
variables.

trouble with plotting data- possible bug?
Hi all,
When I write out some values and then use 'plot' and 'lines' respectively I
can get R to plot me two lines. However when I get the data from a csv file
and run it I only manage to get one line running (whichever was invoked
first). The sample files are attached below and I've reproduced the code
below with the suspicious part marked as #??? (not even sure if thats

getting R to download data
Hi All,
Is it possible to write a program such that it downloads a csv from a given
web address? Would be great if this could be done at a particular time
during the day as well. Say 9AM monday-friday.
Incase you are curious Im just trying to analyse some stocks data.
Thanks,

How to simulate from an estimated density
Hi, dear fellows,
I was wondering how can I simulate from an estimated density function? I
used my training data set and already have estimated density values at some
fixed points. I plan to simulate some data from such estimated density and
compare them to my validation data set. Anyone can help out is really
appreciated. Thanks.

set different font family for strings in mtext or text?
Hi there,
Is it possible to set different font family for strings in mtext or text?
For example, on windows platform with windows() device:
plot(1:10, type = "n")
text(5,5, "Chinese (English)") #Chinese for Chinese characters
it will give the correct Chinese and English characters with two
different font family, i.e., English character in default sans family,
and Chinese

cube root of a negative number
Hi,
This might be me missing something painfully obvious but why does the cube root of the following produce an NaN?
> (-4)^(1/3)
[1] NaN

As we can see:
> (-1.587401)^3
[1] -4

evince not showing "greek" and "math" in *.pdf plots
Hi Martin and Tim,
I also have this bug. Though I think not necessarily with all the same
fonts as Martin.
Using Martin's code:
https://imgur.com/a/ILUoe3H
Fedora 39, Evince 45.0
It's a bug with Evince. I think. I think it's substituting in a font
set that doesn't have all the required symbols. I think it should be
possible to install the required fonts, but I haven't

evince not showing "greek" and "math" in *.pdf plots
Martin, I wouldn't rule out an R issue yet. Fonts are... tricky. So I'm
cc'ing Paul Murrell here.
I tried several viewers here and I see the following: Chrome, Firefox and
Libreoffice Draw show the symbols; however, evince, okular and xournal++
agree on **not** showing the symbols. **If** there is a bug, the bug would
be in fontconfig, because these ones AFAIK properly delegate on

Full_Name: Jaan Vajakas
Version: 2.7.2
OS: Windows XP
Submission from: (NULL) (193.40.5.245)

monotype font in the first plot, but in normal (sans-serif) font in the
remaining three plots:
