Dear list members, I am trying to use the maptools library to display geographical data. At the moment I have some trouble understanding how the " auxvar " variable is supposed to be used in the plot.Map function. I am using R Version 1.8.1 (2003-11-21) on Linux Looking at the plot.Map function itself, I see that it calls a color.ramp function (I am reporting only the relevant

Hello, I can't seem to add transparency to any color ramp I create using colorRampPalette(). Can someone tell me if it is possible to create transparent colour ramps? I am attempting to map shaded relief under elevation data. I know I can use the terrain.colors() with the alpha option, but I would prefer to create my own colour ramp using more vibrant colours. My most recent attempt at

Greetings! I'm having an issue with the windrose produced by the windrose function from the circular package. For our weather stations in North Carolina I'm helping with a script which takes hourly wind speed and direction data to create windroses for our end users. One of the stations in the mountains frequently reaches wind speed of 40 to 60 mph and in storms can reach wind speed over

Dear R users, Could somebody tell me why the grey color ramp is repeated in this graph, eventhough the ramp values go from 0 to 1? I must be missing something obvious, but I can not see it! z <- c(0.064329041,0.117243316,0.161565116,0.19923015,0.231642175,0.259835539,0.284571226, 0.038507288,0.094184749,0.140959431,0.180803984,0.215159105,0.245096084,0.271412845,

Hi, I want to use a discrete color ramp with plot3D, and show NA values as white (default). I get unexpected results per the following. # as in help(slice3D) example: par(mfrow = c(2,2)) x <- y <- z <- seq(-1, 1, by = 0.1) grid <- mesh(x, y, z) colvar <- with(grid, x*exp(-x^2 - y^2 - z^2)) slice3D (x, y, z, colvar = colvar, theta = 60) # # use three discrete classes and colors

Hello All, I have a discontinuous dataset and I used spplot to plot the points. I was wondering whether it is possible to show the legend of the plot as color ramp. I saw that on continuous data. If anyone could tell me that would be great. Another thing I would like to know is how can we create the horizontal legend. By default, the legend is vertical. I was able to shift the legend inside

Dear All: I have a question regarding the behavior of functions. Say I define a function that returns another function : A <- function(parameters) { # calculations w/ parameters returning 'y' tmpf <- function(x) { # function of 'y' } return(tmpf) } The value of the parameters are stored in an environment local to the function. Then I call x<- something

This is a follow-up to my message on R-help about a problem with match.arg() I have a little more on the topic, but not much really. First, it was not entirely true what I wrote in r-help that I call match.arg() in my ramp(), because ramp() just calls qamp() with runif() as

...AMD processors and already properly account for this when using the TSC to derive or interpolate time. C1-state Change =============== The power savings from entering C1-state are enhanced by a feature only recently enabled on multi-processor and multi-core platforms, C1-clock ramping. This feature significantly reduces the power consumption of an idle core that issues the HLT instruction by dividing down its clock rate relative to its current P-state''s input voltage and clock reference rate. When dividing the core''s clock rate down, C1-clock ramp...

Hi Everyone: I'm going a little nuts here and am hoping someone might have some ideas to help out. Here is my problem: I am using the calendarHeatMap function (http://blog.revolutionanalytics.com/2009/11/charting-time-series-as-calendar-heat-maps-in-r.html) to plot some values of percentages above or below a watermark. In other words, I have a time series whose data can range arbitrarily

Hi, I am having trouble debugging this one. The code is attached below, but it seems to be a problem at the C-tk interface. If I run this 1 time there are no problems if I run it more than once I start to get warnings that increase in multiples of 11 everytime I run it. Here is a sample session > source("clrramp2.r") Loading required package: tcltk Loading Tcl/Tk interface ... done

All, I frequently make spreadsheets in Excel in which I rank values in columns by stop-light colors (red is bad, yellow is OK, green is good). Image and heatmap expect a matrix in which all the data are in the same scale, but I frequently have different scales in different columns. ie. Column one runs from 1-10 while column 2 runs from 1-100. I thus need to define a separate color ramp for each

Hi, i created a graph with heatmap(sma) function: heatmap(dataHeat(x)) and I wish to change the gradation of colors from blue to red, how could i do? Using "heatmap(dataHeat(x), col=c(2,4))" i will use only 2 colors without gradation. Ty so much Andrea

I have spatial data on a sphere (the Earth) for which I would like to run an gls model assuming that the errors are autcorrelated, i.e. including a corSpatial correlation in the model specification. In this case the distance metric should be calculated on the sphere, therefore metric = "euclidean" in (for example) corSpher would be incorrect. I would be grateful for help on how to

Hi all, I had the need to create a colorbar considering the alpha channel of the colors, but colorRamp() and colorRampPalette() ignored the alpha argument in rgb(). So I performed some minor modifs. in their codes, as to support the interpolation using the alpha channel. I guess that those simple modifications might be useful for other people, so perhaps it would be worth to add them to

...ut from ogg123, not from other programs (mpg123, for example) with effectively the same sound sample. Case 2: sample rate "ramp-up" First second starts at too low a data rate and corrects over about a half second's time, resulting in the pitch ramping up to the right pitch. Only occurs with esd. Does not occur with mpg123 on original mp3 file. Does not occur when using oss mode. Is not random, i.e. if it occurs once with a given .ogg file, it will always occur with that file (but goes away if you switch to usi...

Hello Everyone, I''d like to just officially announce that the new volunteers are in charge and given control of the project. I won''t be doing anything more than helping them get ramped up, but they''ll be in charge of doing all the stuff you folks want and are basically the owners from now on. Everyone in the new volunteer list will probably do a little announce, but
