overlaid filled contour plots
I'm trying to make a set of contour plots of bivariate kernel density
estimates, showing three such plots overlaid,
similar to this plot
http://euclid.psych.yorku.ca/SCS/Private/Test/ridge-boot2.pdf
except that I would like to have the contours *filled* (using
transparent colors). To make this reproducible, I've
saved the results of KernSmooth::bkde2D() in the following file:

help with filled.contour() -
Dear all,
I can't figure out a way to have more than one plot using filled.contour() in a single plate. I tried to use layout() or par(), but the way filled.contour() is written seems to override those commands.
Any suggestions would be really appreciated.

Contour plot (level curves)
Hi all,
I have a sample of n values from a bivariate distribution (from a MCMC
procedure). How could I draw a contour plot of "the joint density" based on
that sample ?
Sorry if I was not too clear.
Thans in advance,
Regards,

about contour - get contour coordinates - exclude area display
Dear all,
I wonder about what could actually be possible with the function "contour":
1/ - the definition of contour lines is most often meaningless when the contours are drawn in areas where no real data points exist.
It can however happen that irregular distributions lead to more or less irregular clouds of data points. Interpolations (eg: loess
regression, GLM, etc...) are however

contourplot:how to get it to label all contours like 'contour'
Hi,
one of the nice things about contour is that it labels all contour lines.
contourplot only labels each particular elevation a single time.
i.e., if there are two contour lines corresponding to z = 45, it will only
label one of them.
is there a way to get contourplot to automatically label all the contour lines,
even those that are repeated?
i ask because i want to plot contour plots *w/

Labelling contour lines
I am using contour to draw contour lines onto a photo (jpeg) of a leaf on
a white background.
I have two problems:
1) The contour gets plotted at right angles to the jpeg image. I guess
this is a problem of referencing the start and end points of the image
matrix but I can't see how to over come this other than loading in a
second image that has been rotated 90 degrees and plotting the

Center of Closed Contour
I am searching for a utility in R which will determine the mean location of
a closed contour and eventually record the location in an ASCII file. By
means of the contour utility in R, I am able to produce an image of a contour,
but I am seeking a procedure which will produce the coordinates of the
center of mass of the contour. From my actual set of data, the contour
utility will produce several

dotted contour line for negative values?
I have a contour plot where the surface can take on positive and negative
values. I would like to use solid contour lines for positive values and
dotted contour lines for negative values. I saw a plot like this produced
by S-Plus before. Is there a way to do this with R? If not, can anyone
suggest a way to make interpretation of the contour plot easier? (Right
now, it is not clear if a set of

contour() & contourLines()
Hi Folks,
I have been using contour() to produce some contour plots
(of a spatially-smooted density produced by kde2d()), with
very satisfactory results.
I now want access to the coordinates of the points on the
contours, and it would seem that contour() does not return a
value, so there is nothing from which these could be extracted.
However, apparently contourLines() does, and it seems to be

adding contour lines to a filled.contour
Hi all,
Does anybody know how to add contour lines to a filled contour plot?
I want to draw a single contour around values that are above a certain
level (e.g., significant). The problem I'm having is that since the
filled.contour command actually draws two plots (data and the key),
adding contour lines paints them over both plots.
Any suggestions?
Thanks, Andy

contour algorithm
First time user, so sorry if I don't understand protocol.. Anyway, I have
created a data frame consisting of pearson's R values at various x and y
coordinates and then plotted this using filled.contour. My data is similar
to fMRI data except that it is a surface map reconstructed from
histological sections. I like the results but would like to know how
contours were detected. Google search

smooth contour lines
Is there an easy way to control smoothness of the contour lines?
In the plot I am working on due to the undersampling the contour
lines I am getting are jugged, but it is clear "by eye" these should
be basically straight lines.
In maps package I found smooth.map function, but maybe there is a more
generic way
of accomplishing the same thing.
Ideally there would be an option to control

A contour plot question - vis.gam () function in "mgcv"
Hi,
Please see the attached contour plot (I am sorry about the big file). This was created using the vis.gam() function in "mgcv" package. However, my question is somewhat broader.
In generating this figure, I first created the contours using vis.gam() and then I plotted the points. These point are plotted on top of the contours so that some of the contour lines are only partially

contour(): lines & labels in different colours?
Greetings, All!
I want to draw contour lines in red, using contour(), but also
have the contour labels (for the level-values) in black so that
they will stand out against a coloured background already generated
using filled.contour() (the background shades from green at low
levels of "risk" to red at high levels).
In any case, contour labels in red are already somewhat inconspicuous

asking about contour plot with R
I'm working in Rosario, Argentina, trying to plot some contours.
I found the function "draw.contour" created by James Forester at
R-bloggers. If you take a look at that function you'll see it's very
useful!
But I have a problem with it and James is trying to help me (but also
asked me to seek for more help) I hope you can help me (don't worry if you
can't):

Plot contour inside a polygon
Dear,
I am trying to plot contours (with filled.contour function) inside UK area, so that no contours are plotted over the sea. I was wondering if anyone can help me with this task and if I can get any suggestions how to do that.
Thank you,

numerical issue in contour.default?
Dear R developers,
I found a small issue while plotting contours of data containing both
"usual" and "very small" numbers. It appeared with both R 3.0.1 and
R-Devel on Windows, and I could reproduce it on Linux. Would it be
possible to solve this before the upcoming release?
Thanks a lot for developing this great software!

I was wondering if anybody can help me solve 2
