Request - adding recycled "lwd" parameter to polygon
Hello dear members of R-help and R-core mailing list,
I am not sure if this request is a "ticket" that should be filled somewhere
outside the mailing list. If so, I apologize for not doing and would like
to know where I should have filled it.
And to the subject matter:
I would like to use a command like this:

Filling graphic objects
I have used polygon() to mark the confidence limits of a survival curve.
In another project, I have used the col parameter to fill my boxplots.
The poly() description refers to filling but actually produces
hatching (i.e. lines ).
boxplot() does truly fill the boxes with a colour or shades of grey
(e.g. col="red").
My novices perception of R graphics is:
If you can hatch it, you

Selectively shading areas under two density curves
Dear Listers,
I am drawing a plot of two density curves, for male and female incomes. I would
like to shade/hatch/color (whatever) the areas under the curves which are
distinctive for each gender. This is the code I have tried so far:
m <- density(topmal.d$y, bw = "sj")
f <- density(topfem.d$y, bw = "sj")
par(mfrow = c(1,1))
plot(x = c(0,400), y = c(0,0.02), type =

polygon angle option perpendicular to axis
Thanks for the question. Here is a sample of the code for my plot:
Top = c(34, 39, 42, 45, 46, 41, 41, 40, 43, 38, 33, 33)
Bottom = c(24, 29, 32, 36, 32, 34, 32,41, 40, 39, 29, 24)
plot(1,1, col = "white", xlim = c(1.3,11.7), ylim = c(0,80), axis = FALSE, xaxt = "n")
axis(1, at = c(1:12))

Density estimation graphs
Dear all,
I'm struggling with a plot and would value any help!
I'm attempting to highlight a histogram and density plot to show a
proportion of cases above a threshold value. I wanted to cross-hatch the
area below the density curve. The breaks and bandwidth are deliberate
integer values because of the type of data I'm looking at.
I've managed to do this, but I don't think it

polygon angle option perpendicular to axis
Tena koe Simon
plot(1:10, 1:10, type='n')
polygon(c(2,3,6,8), c(2,5,5,3), density=20, angle=90)
polygon(c(2,3,6,8), 5+c(2,5,5,3), density=20, angle=0)
I don't understand your problem. Perhaps if you "provide[d] commented, minimal, self-contained, reproducible code" it would help.

Help with shading a polygon below a segment of a curve (normal distribution)
Dear R users,
I still feel new to R so please apologize if I am doing something stupid
here. My use of the polygon() function produces a result that I cannot
comprehend: In a plot, I would like to shade the area below a normal
distribution. However, I do not want the entire area to be shaded, but
just the area on the right side of a vertical line that I draw through
the distribution (in

Polygon function
Dear all,
I would like to plot credible interval for a function estimate in R. I
would like to plot the credible intervals as shaded region using polygon
function. Does anyone ever used that? I tried several times but I could
not obtain the right figure.
xis=sort(xi,decreasing=TRUE)
plot(xi,fm)
polygon(c(xi,xis),c(f05m,f95m))
The above piece of code produces something else.
Many thanks in

converting histogram to barchart
Hi list,
After a lot of tweaking i have managed to create a histogram with an
overlaying density plot. The histogram shows a sample of birth weights
of babies and the density plot shows birth weights from a much larger
reference populaton. My data is divided in 0.1 Kg bins so in the code
below binweigh=0.1.
The trouble with the current graph is that it is not very clear since

superpose.polygon, panel.polygon and their colors
Dear R-helpers,
the problem I'm facing today is to convince lattice to paint some areas
in gray.
The areas I would like to have in gray, are confidence bands
I've googled around in the mailing list archives and eventually find
some clues.

polygon angle option perpendicular to axis
I am trying to use the angle option in polygon to create polygons filled with horizontal and vertical lines. The polygons I am crating are irregular and it the angle function appears to set the angle of the shading perpendicular to the polygon sides rather than perpendicular to the axes. Is there any way to set the angle relative to the axes rather than relative to the polygon sides?

Can levelplot colorkeys display a logarithmic scale evenly?
I'm using the {lattice} "levelplot" function to make a (more or less) 2-d
histogram, and for the most part it's working fine with my data. However, I
can't get the color key to do what I need. I can give it labels and custom
cutoffs, but my cutoff lines (and hence my labels) aren't evenly spaced, instead
they're more-or-less logarithmic, starting at

Polygon shaded area
Hi all,
I have two vectors (columns) called "efinal" and "efinal 2".
I want to plot them on the same plot and "draw" a shaded area beween the
two lines using function polygon
I have tried all but I don ?t understand the polygon area, can you help me
with examples?

Determine if a set of x and y-latitude points are inside of a polygon using R
Objective: Determine if a set of x and y-latitude points are inside of
a polygon using R.
Lets say I have 9 polygons. Where I have labeled the polygons to be
checked from 1-9. The problem I?m running into is running the
point.in.polygon to check if those points are in one of several
polygons, as my code overwrites the result.
To accomplish this I am using the R-built in function called

How do I ensure that the polygon in spatstat::owin(poly=<polygon>) does not have “negative area”

shading of curves with polygon
Hello again
With the poylgon function it's possible to plot shaded areas under a curve.
But somehow it connects the start and the endpoint of a line and fills whats between them. I would actually like to set the boarders of the shading by two min and max curves, but I failed.
i tried stl like:
polygon(min, max, border=0), where min and max are my curves plotet by plot(max)
lines(min)

Draw Polygon with a Circular Side
Hello Friends!!!
I would want draw a circular histogram, and I would like draw a polygon with
a circular side. This is easy if I use the functions polygon and arc, but I
want that the polygon with a circular side have background colour. The
polygon created with function polygon can have background colour, but the
surface created with function arc can?t have background colour.

attempt at making a polygon class failed

point.in.polygon() in sp package: accuracy problems?
Dear list:
I encountered some problems using the function point.in.polygon() of the sp package, when trying to determine whether some points lye inside, outside, on the border or on a vertice of a polygon.
I have a list of point I know should lye right on the border of a polygon, but some of them are not classified as such by point.in.polygon() (see the example code below).
