Hi Mackay and anybody (a) Is it possible to select randomly (let say five grids) and plot? (b) Is it possible to plot five nearest grid in one figure? The original question and improved codes: #I am ploting gridded time series data. I would like the actual lat #and lon value appear on the graph-if possible inside the graph as #numbers. If there is also more elegant ways to plot the graphs I

hello, all. one of my students is having an issue with the pie & legend function. this is her code. (below) it works just fine for me. her error is "plot.new has not been called yet". i know this means her pie chart is coming up blank so the legend will not work. according to ?graphics this package *is* supposed to handle these functionalities. however, when i tried to

????? The ":::" operator doesn't work for me with "Ecdat:::Crime" on either macOS 10.15.3 or Windows 10. ????? A different but related issue is that "plm::Crime" says "Error: 'Crime' is not an exported object from 'namespace:plm'", even though "library(plm); data(Crime); Crime" works.? I would naively think a user should

Hi, Last week my class conducted an experiment by putting out clay caterpillars to look at the effects of urbanization, color, and location on caterpillar predation. There were two sites (urban, rural), three colors (green, yellow, red) and two locations at each site (edge, interior). The entire data set is below. I've checked out the MASS book, Dalgaard's book, and the R-help archives

Hello: I need to create a six barplots from data that looks pretty close to what appears below. There are two grouping variables (age and gender) and three dependent variables for each grouping variables. I'm not really familiar with trellis graphics, perhaps there is something that can do what I need there, i don't know. The thing is: I *need* these to appear on one row, with some way

Dear R-users, I set up an experiment where I put up bluebird boxes across an urbanization gradient. I monitored these boxes and at some point I pulled a feather from a chick and a friend used spectral properties (rtot, a continuous var) to index chick health. There is an effect of sex that I would like to include but how would I set up a regression and look at the effect of urbanization

Hi, Some of you have heard of CRIME, probably. from https://bugzilla.redhat.com/show_bug.cgi?id=857051 > Adding the following line to the /etc/sysconfig/httpd file: > > export OPENSSL_NO_DEFAULT_ZLIB=1 But there are other services but http that use ssl and are vulnerable?

I'm very new to R and I'm having trouble doing something that should be very simple (so I'm probably missing something quite obvious). When I run > lm(data$CRIME~data$INCOME+data$HOUSING) I get the correct coefficients. However, when I try to get anything else out of this I get a message about a missing argument, e.g.: >

Greetings- I have a strange problem displaying a graph from R (1.3.1, linux) in a LaTeX document of documentclass seminar. I'm using graphicx to include the file: \usepackage{graphicx} ... \resizebox{\textwidth}{\textheight}{\includegraphics{crime.eps}} When I do this, the entire slide (including the page number) is rotated 180 degrees. Any ideas why this happens? The graph was created

Earlier today I posted a problem importing an R graph into a LaTeX file of seminar class: specifically, the graphic was showing up rotated 180 degrees, along with the rest of the page it was on. In a real victory for open-source software, I got lots of responses with three distinct approaches, each of which appears to solve the problem.

Hello, we want to plot a proportional symbol map with ggplot. Symbols' area should have the same proportions as the scaled variable. Hereby an example we found on http://www.r-bloggers.com/bubble-chart-by-using-ggplot2/ . In this example we see the proportions of the symbols' area are different from the proportions of the scaled variable: crime <-

Also nice to know that zlib at openssh.com enables the compression only after authentication, mitigating the known problems with compression and passwords. It is also very hard to do chosen-plaintext attacks on the client to server side (in opposite to HTTPS where that's trivial). And most passwords that are typed after authentications are entered character by character, making them fall under

I am looking into using the multinomial logistic regression option in the nnet library and have two questions about formatting the data. 1.

Compressing data before encryption may be dangerous, for example CRIME, BREACH and VORACLE. Can compression be disabled by default in OpenSSH, only being enabled if user requests it? Another scenario when SSH compression may be bad is use of commands like tar cz | ssh root at remote "tar xz", which seem pretty common. If SSH compression is enabled, data will be (wastefully) compressed

Greetings R users, I am an R graphics newbie trying to produce a custom trellis plot using pairs() with R 2.7.2. I have spatial data on which I run a geographically weighted regression (gwr, using the -spgwr- package). I want to check the gwr coefficients for multicollinearity and spatial association, following Wheeler and Tiefelsdorf (2005), and I would like to summarize the results of this
