Plotting a vector data
Hi; I have 30 data sets and I managed to take the average of a variable in each set and put them in a vector like variable(It contains NaN data as well). x<- matrix( list.files("C:/updated_CFL_Rad_files/2007/11",full=TRUE)) for(i in 1:30) { radiation.data <-read.table(x[i], header = TRUE,sep = ",", quote = " ", dec = ".") attach(radiation.data) names(radiation.data) mean.radiation[i]<- mean(PAR_avg,na.rm = TRUE) } How can I plot this vector (mean.radiation[i]) vs i ? I tried to do so but there...

[OT] Video card radiator
I recently obtained a desktop computer with an nVidia video card: from lspci: 02:00.0 VGA compatible controller: nVidia Corporation G84 [GeForce 8600 GT] (rev a1 I had to open the case to connect the DVD drive and saw what appears to be a fallen radiator: http://www.cs.ndsu.nodak.edu/~hennebry/computer/amd64-1.jpg http://www.cs.ndsu.nodak.edu/~hennebry/computer/amd64-2.jpg That nothing is shorted

Extending a plot in a loop
...t one parameter of the data for all the days in one graph. I tried to use for loop but only the last data remains in the program memory, I don`t know how to plot each day`s data continusly after the others(or how to extending the x axis.) Would you please help me with it? This a plot for one day: radiation.data <-read.table("C:/updated_CFL_Rad_files/2008/RAD_2008_JD101_0410.dat", header = TRUE,sep = ",", quote = " ", dec = ".") > attach(radiation.data) The following object(s) are masked from 'radiation.data (position 3)': Batt_avg, Batt_st, D...

is aov equivalent to lme for split-plot analysis?
Dear R community, I am trying to do a split-plot analysis as follows. I have a data set (?morf?) with plant data from 6 ?blocks? at different latitudes, each divided in 3 plots. The full-plot ?treatment? is ?soil type? and has three levels. Within each plot I have two levels of radiation, coded as ?SUN? and ?SHADE?. I have data for several response traits for 30 plants within each subplot, that is 1080 plants in total (6 Blocks x 3Plots x 2Radiation levels x 30 Plants). I want to measure a) if there are differences between latitudes (?blocks?) and b) how these differences inter...

WiFi phone radiation regulation?
All, I just had the fortune to take one of the new Senao Wifi SIP phones for a short test drive. First look - it's a nice, compact phone. Weighs around 87g and roughly the size of a Nokia 6210. More on the those later. The thing that struck me was the RF power, it's rated at 100mw (20dBm). That's 10 times more than any of the other brands out on the market Cisco, WiSIP, Zyxel

add one point to contourplot()
Hi All, I want to add one point to contourplot().  I used contourplot() in my code like contourplot(z ~ a + b |c, data) I understand there is plot.axes argument for filled.contour(), but it  did not work for my code. I also tried plot() and text() for contourplot(), but got this error: "plot.new has not been called yet" Any suggestion for adding a point in contourplot()? Thank you very

change lattice panel background color
I can't find a way to change just the panel background color in lattice. I would like NA regions in levelplot() to appear black. I've tried the trellis.par.set() stuff, but it it makes the background of the whole graphic black. Thanks, Scott Waichler Pacific Northwest National Laboratory scott.waichler _at _ pnl.gov

Interpreting summary of lme
Dear mixed-modelers, I have built a mixed model and I'm having serious trouble with interpreting the output. I want to test differences in the coefficient of variation (CV) of light across 3 tree crown exposures (Depth). I have measured direct and diffuse radiation (RF) and I want to test for differences for each kind of radiation between crown exposures, as well as differences between radiation fractions at each crown exposure. I have sampled 5 individuals (Ind) at each of 2 populations (Pop), thus individual is nested in population. I have repeated the expe...

(no subject)
Good morning, I wrote a little code in R which has to show two graphs but I can get only one. How can I adress the graphs in two files? Second, I'd like, always in the same code, to add a legend to a graph. Better, I'd like to put in such a legend a new item whose color could remind the colour ol the columns it refers to in the plot. I wrote: leg.txt<-c("control

FS corruption? bogus i_mode
Hello, I am doing some testing on a PXA270 based processor (on a single board computer) which makes the processor vulnerable to bit flips. One such bit flips seems to have corrupted the file system. The debug port on the board (it is a single board computer) had the following message when i think the FS corruption occured : <7>init_special_inode: bogus i_mode (33061) init_special_inode:

3D plot with coordinates
Thanks Duncan for the replyI can not suppress anything these are radiation pattern measurements that are typically are taken at X,Y and Z planes. See an example here, where I want to plot the measurements for the red, green and blue planes (so the image below withouth the 3d green structure inside)https://www.researchgate.net/publication/258391165/figure/fig7/AS:322947316...

Perl fun part 2
I figured this needed it's own thread, so apologies for spamming the list. Along with the /usr/share/perl5 issues (which I did kinda fix with a manual copy of the directory from another box), we're having an issue with SystemD (go figure) stopping the radiator service, but failing to unbind the ports (1645/1646). It's complaining about 'killproc' not found. Is there a

Authenticating users via samba to an active directory
Chaps, Got a small problem here that I could do with some help with. I am looking at implementing 802.1X wired based network authentication here and am using a RADIUS server called Radiator as the primary authentication mechanism. Radiator has an authentication module that'll allow user auth to an active directory via components of the samba suite. The requirement is that the host samba

Getting started help
Hello, I need to learn to use r-software for my PhD research project involving long timelines of radon radiation variations. I am using windows. I am currently discouraged by the use of r. I cannot figure out how to use it despite extensive searches. Can anyone help me with getting started? How can import a txt file with series of numbers from the RAD7 machine? How can I open up and set directories with the...
