Wishlist: specify the border color of boxes in legend() (PR#13913)
I could not find a way to specify the border color of the boxes drawn in
a legend, so that the legend can match exactly the colors of the actual
plot (e.g. in the case of two superimposed histograms which have
different shading and different borders).
Indeed, the legend function seems to hard code the color "black" for the
borders in this call:
rect2(left = xt, top = yt +

whishlist: legend - changing color of the boxes-border
Hi,
Drawing a legend I would like to be able to specify the color of boxes which are drawn if fill or density is specified.
eg.
legend(0,40000,c("raw","LR/PR-TPS"),fill=c(1,2),col=c(1,2),density=c(20,20),angle=c(-20,45),bty="n")
Currently the color of the boxes -- border is always black and can *not* be changed. To get this option only a *minimal* change is

colorbar legend for image()
Hi,
are there any plans to add a colorbar legend to image()?
Or such a possibility already implemented which I just haven't
discovered yet. Anyway, I will be willing to spent some time on the
implementation if there isn't anyone working on that already.
Thanks
Thomas

legend()
In legend() is it possibly to mix lines and boxes? I would like to do
something like
legend(locator(1), legend = c("al", "ben", "chris", "dave"), lty =
c(1, 2, 3, NA), fill = c(NA, NA, NA, "gray"))
to indicate that "al", "ben" and "chris" have lines, and "dave" has a gray
shading.
Many thanks,

R-alpha: Logarithmic scales
Here are another three problems with logarithmic scales:
1) segments() does not work with logarithmic scales. I suggest to change
lines 962-973 in "plot.c":
for (i = 0; i < n; i++) {
if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0]))
&& FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) {
GP->col = INTEGER(col)[i % ncol];

"trace" argument in legend() (PR#2578)
Full_Name: Jerome Asselin
Version: 1.6.2
OS: RedHat Linux 7.2
Submission from: (NULL) (142.103.173.179)
Should be an easy fix...
Consider the examble below:
plot(0,0)
legend(0,0,c("Hello!","Hi!"),pch=1:2,lty=1:2,trace=T)
It gives the following trace:

Masking oceans using polypath
Hi R-help
I am trying to mask the ocean from an image plot I have made.
Here is some example code:
library(mapdata)
image(x=110:155, y =-40:-10, z = outer(1:45, 1:30, "+"),
xlab = "lon", ylab = "lat")
outline <- map("worldHires", plot=FALSE) # returns a list of x/y coords
xrange <- range(outline$x, na.rm=TRUE) # get bounding box

R-alpha: various graphics Q.
"contour" can't return a list of contours (it would be nice)
"arrows" has different options from S-PLUS (no "open" or "rel" options,
no "lwd" parameter or graphics parameter pass-through; "size" in S
corresponds to "length" in R). [I know we needn't follow S-PLUS syntax
slavishly, but it would be nice at least to

legend with multiple columns
I have made a minor hack to "legend" (in R 1.0.0, but I didn't notice
any changes to legend in the 1.0.1 NEWS) to allow the legend to be
formatted in multiple columns, or horizontally (number of columns <-
number of legend items). (I find this helpful when I have lots of legend
items and not a lot of vertical space to squeeze the legend into.)

Error in 'legend' help?
Dear all,
maybe I have misunderstood something but to me it seems like a minor error
in the help for
?legend
for the argument 'bg'. There it says:
bg: the background color for the legend box. (Note that this is
only used if 'bty = "n"'.)
I think, however, that it should be changed to:
bg: the background color for the legend box. (Note that this

Clip a contour with shapefile while using contourplot
Hi, I have done the interpolation for my data and I was able to create the

displayed which falls inside the boundary of the shapefile.

Constructing an environment from a data.frame
Code like
df <- data.frame(x=1:10)
y <- 20:29
eval(quote(x+y), env=df)
does what you might expect: it looks for x and y in the data.frame,
and when it doesn't find y there, it looks in the parent environment.
However, sometimes I'd like to construct a single environment out of
df, so that I can pass it to nested functions and get the same
behaviour. Right now, I get the wrong

panel data unit root tests
When finally got some time to do some coding, I started and stopped right
after. The stationary test is a good starting point because it demonstrates
how we should be able to move the very basic R matrices. I have a real-
world small N data set with
rows:
id(n=1)---t1---variable1

id=(N=20)---T=21---variable1
Thus, a good test case. For first id I was considering something like this:

colnames slow (PR#10470)
Full_Name: Tomas Larsson
Version: 2.6.0
OS: Windows XP
Submission from: (NULL) (198.208.251.24)
This is not a bug, it is a performance issue but I think it should have an easy
fix.
I have a large matrix (about 2,000,000 by 20), when I type colnames(x) it takes
a long time to get the result. However, if I select just the first couple of
rows of the matrix I don't have to wait for the
