Yes, . But I am a long-time user of the rms/Hmisc combo, as well as the
survival package, so near the top of my .Rprofile is:
require(lattice)
require(sos)
require(rms)
Should I be ashamed of that?
I suppose I should, and I _am_ ashamed of some of the other stuff in there
, ... and I've been meaning to address my manifold
deficiencies w.r.t. irreproducibility by moving to RStudio, but I keep putting

Sigh. I never load packages in .Rprofile to avoid the irreproducibility trap.
Might seem drastic to some, but I don't feel much pain because I almost always
edit my code in a file rather than on the fly at the console, and re-run it
frequently from a fresh R process to check my progress.

Package 'scales' has the alpha function... associated with ggplot2. A bit out
of place here if that is the origin. Yes, we are squarely in non-reproducible
example territory, also known as the Twilight Zone.

I discovered some time ago that I no longer needed to load the ggplot2 package.
I wasn't entirely happy to make this discovery since I stilll cling to the old
lattice style. Eventually I figgured out that it was because one of packages
that I load in my .Rprofile-file had changed its imports. The `alpha` function
I see is from ggplot2. Resistance is futile. I've now been partially
assimilated.

Re: [R] [FORGED] Re: draw stripes in a circle in R
Hi Jean-Phillipe,
Thanks for the plug on plotrix. Because of that I will suggest a gross
hack that will do almost what you want:
# your code down to draw.circle
segments(c(-12.7,-12.7),c(-11.2,-10.6),c(-12,-12),
c(-10.75,-10.15),col="white",lwd=28)
draw.circle(-12.85,-10.9,0.85,nv=1000,border=NULL,
col=NA,lty=1,lwd=1)
box()
dev.off()
Your problem is that plotrix is written in base graphics, which is
simple to understand, but does not support layered graphics. Thus I
have to do the striping over the yellow circle and avoid overwriting
the big red stripe. You should do this using the grid graphic system,
but that would take too large a chunk of my morning to write an
example for you.
To Rolf - It happened to me as well, but because I saw Venus smiling
at me in the sky this morning I was granted the knowledge that it was
a function that had not been properly introduced to us and simply
replaced it with "red". Such are the benefits of evidence-based
astrology.

This is just idle curiosity, since I'm not really able to contribute
anything useful, but I can't resist asking: When I try to run the OP's
code I get an error:
> Error in alpha("red", 0.4) : could not find function "alpha".
Sorry for the lack of precision, alpha is just to add some transparency to the
color. This alpha parameter ranges from 0 fully transparent to 1, full color.I
don't remember having loaded any package to use this function, I think it is
there in base R.
Why does this (apparently) not happen to anyone else? Why does the
universe pick on *me*? What is the function "alpha()"? Where is it to
be found?
Searching on "alpha" is of course completely unproductive; there are far
too many (totally irrelevant) instances.
cheers,
Rolf

Re: [R] reading data
Hi Jim,
With a little dig on my side , I have found the issue as to why the
script is skipping that file. The file is "ISO-8859 text, with CRLF
line terminators"
The file should be ASCII and I changed using dos2unix and CRLF line
terminators is eliminated but still I am not reading it. How can I
read those files with "ISO-8859 text"?

Agree that the coding question remains unclear, so not using the offered
example but responding to the natural language query. The `polygon` function
has 'density' and 'angle' argument that with 'col' and 'lwd' can make slanted
fill lines. This is a modification of hte first example on `?polygon`?
x <- c(1:9, 8:1)
y <- c(1, 2*(5:3), 2, -1, 17, 9, 8, 2:9)
op <- par(mfcol = c(3, 1))
for(xpd in c(FALSE, TRUE, NA)) {
plot(1:10, main = paste("xpd =", xpd))
box("figure", col = "pink", lwd = 3)
polygon(x, y, xpd = xpd, col = "orange", density=3, angle=45, lwd = 5,
border = "red")
}
The polygon function is _not_ in pkg::plotrix.

Re: [R] draw stripes in a circle in R
Sorry for that. Yes my question was whether or not and how is it possible to
fill a circle of yellow stripes in R? Is it something that I have to precise in
the color argument?
Thanks, best

I don't see a question. If your question is whether R supports pattern fills,
AFAIK it does not. If that is not your question, ask one.

Re: [R] draw stripes in a circle in R
I don't see a question. If your question is whether R supports pattern fills,
AFAIK it does not. If that is not your question, ask one.

[R] draw stripes in a circle in R
dear R users,
I would like to fill a circle with yellow stripes instead of a uniform
yellow color. To draw the circle I used the following command after
having loaded the (very nice !) plotrix library :
library(plotrix)
pdf("MWE.pdf",width=8, height=8)
plot(seq(-12.5,-8.7,length.out=100),seq(-11.3,-8.3,length.out=100),type="l",col="red",xlim=c(-12.5,-8.7),ylim=c(-11.5,-8.5))
par(new=T)
plot(seq(-12.5,-8.7,length.out=100),seq(-11.7,-8.7,length.out=100),type="l",col="red",xlim=c(-12.5,-8.7),ylim=c(-11.5,-8.5))
par(new=T)
polygon(c(seq(-12.5,-8.7,length.out=100),
rev(seq(-12.5,-8.7,length.out=100))), c(seq(-11.3,-8.3,length.out=100),
rev(seq(-11.7,-8.7,length.out=100))),
col = alpha("red",0.4), border = NA)
par(new=T)
draw.circle(-12.85,-10.9,0.85,nv=1000,border=NULL,col="yellow",lty=1,lwd=1)
dev.off()
It looks a bit ugly since they are not real data, but it is the simplest
MWE example that I found.
Thanks, best
Jean-Philippe

Re: [R] Plot MArginal distribution in the correct place
Please can you send me some orientation?
Many thanks in advance.
Only if posible one book o similar example to understand why it is not what
I try.

Re: [R] Plot MArginal distribution in the correct place
Hi Pedro,
If you keep that same margins for the second plot:
par(mar=c(10,0,6,6))
barplot(fhist$counts,axes=FALSE, space=0,horiz=TRUE,col="lightgray")
it looks reasonably well aligned to me. Because you are plotting the
counts of the values in Simulation, the ordinate (vertical axis) of
the bar plot is in quite different units from that of the plot on the
left side.
