similar to: Plot of function seems to cut off near edge of domain

If you have "value" as a function of latitude and radius, isn't that a 2D (not 3D) scalar field? Which can be plotted using a regular heatmap. If you want a curved edge where depth=0 (radius=?), that's not too difficult to achieve. Not quite sure what continent boundaries mean in this context, but that could possibly be added to. Or do you want a 2D slice superimposed within a

1. Have you looked here: https://cran.r-project.org/web/views/Spatial.html (I assume you have done some web searches on possible terms like "3D Earth Data R" or whatever) 2. You might try posting on the r-sig-geo list rather than here, where relative expertise may more likely be available. Cheers, Bert Gunter "The trouble with having an open mind is that people keep coming along

Thanks for your idea. It should be a 2D slice/plane embedded into a 3D space. Could be static, I just need to make a single figure from it for illustration of the Earth together with its interior in 3D. So, the interior would be a slice in 2D along a fixed longitude. And along this 2D slice would be a heatmap. Again, embedded in 3D, since it would be shown as a slice of Earth in 3D. Duncan?s

Dear All: Thank you very much for all of you. I just have one more thing. Is there a way to fill the borders with small dots, may be different sizes. I tried to do it, but it looks ugly. Here what I tried: library(plotrix) plot(0:10, 0:10, type="n",axes=FALSE,xlab="",ylab="") #### 0:5, draw.circle(4,5,radius=3,border="#ff0000aa", lwd=75)

Hello, Could someone suggest a package/way to make a 3D raster plot of the Earth (with continent boundaries), and then make a "cut" or "slice" of it such that one can also visualize some scalar quantity as a function of the Radius/Depth across that given slice ? Formally, I would have a given, fixed longitude, and a list of vectors {latitude, radius, Value} that would show

Dear Researchers, I wrote two function to fit a circle using noisy data. 1- the fitCircle() is derived from MATLAB code of * zhak Bucher* from the link http://www.mathworks.com/matlabcentral/fileexchange/5557-circle-fit/content/circfit.m 2- the CircleFitByPratt() from MATLAB code of *Nikolai Chernov *from the link

Dear List members I am trying to find a way to generate a random point in a circle centred in a geographical location. So far I have used the following formula (see code below): random_x = original_x + radius*cos(angle) random_y = original_y + radius*sin(angle) where radius is a random number between 0 and the radius of the circle and angle is between 0 and 360 degrees The code bellow works

Here is a potential wishlist item for adding an argument (asp) to symbols(). The following code produces a postscript file with two pages; both should show a circle of radius 2 units. Horizonal and vertical arrows are drawn to check that the circle is of the correct radius; in the first plot, the circle is wrong. To fix this, I found that I needed to first set up the plot bounds, using xlim,

hi david Thank you very much for the hack of draw.circle that you proposed me. I don't understand some part of the code, why do you pass radius as a vector in the function (if I understand well the purpose of the for loop) ? Also what is ymult? If I set the radius to the value 0.85 as I wanted (so as a scalar), I don't see any difference in the result when I call this function

Another solution: library("HelpersMG") plot(0:10,type="n",axes=FALSE,xlab="",ylab="", asp=1) ellipse(center.x = 3, center.y = 5, radius.x = 5, radius.y = 5, lwd=10, col=NA, border=rgb(red = 1, green = 0, blue=0, alpha = 0.5)) ellipse(center.x = 8, center.y = 5, radius.x = 5, radius.y = 5, lwd=10, col=NA, border=rgb(red = 0, green = 1, blue=0, alpha =

Sigh. I never load packages in .Rprofile to avoid the irreproducibility trap.

Hi, I don't think this is a bug, but I thought I'd mention it in case others think it is not correct... I guess it is probably just a rounding error. If I use symbols() to draw some circles, any circle with radius of zero gets drawn as a small circle. As an example: postscript(file="test.ps") symbols(1:9, rep(2,9), circles=seq(from=0.05, to=0.0, length=9),

Hi there, SuSE 8.2 Prof.+Samba 3.0.3 / WinXP Prof clients: I made a script to create new users (creates homedir, sets permissions, creates personalized logon-batch, creates smbpasswd and something more). When the new user logs in for the first time from the client-machine (domain-logon, only domain-users, no local users), he gets default profile with the xp-style menus and so on. I tried
