I have been trying to read in a large data set using read.table, but I've only been able to grab the first 50,871 rows of the total 122,269 rows. > f <- read.table("http://www.cs.odu.edu/~fmccown/R/Tchange_rates_crawled.dat", header=TRUE, nrows=123000, comment.char="", sep="\t") > length(f$change_rate) [1] 50871 From searching the email archives,

Dear All, I would like to be able to plot histograms/densities on a semi-log or log-log scale. I found several suggestions online http://tolstoy.newcastle.edu.au/R/help/05/09/12044.html https://stat.ethz.ch/pipermail/r-help/2002-June/022295.html http://www.harding.edu/fmccown/R/#histograms Now, consider the code snippet taken from http://www.harding.edu/fmccown/R/#histograms # Get a random

Hi, I have installed R 2.15.2 on windows 7. http://cran.cnr.berkeley.edu/ I tried to run some simple graph code: http://www.harding.edu/fmccown/r/ But, no graphs are presented or poped up. Any help will be appreciated. Thanks [[alternative HTML version deleted]]

Is there a simple way to put a legend outside the plot area for a simple plot? I found... (at http://www.harding.edu/fmccown/R/) # Expand right side of clipping rect to make room for the legend *par(xpd=T, mar=par()$mar+c(0,0,0,4))* # Graph autos (transposing the matrix) using heat colors, # put 10% of the space between each bar, and make labels # smaller with horizontal y-axis labels

Hello fellow R users, I have a problem. I have created a barchart overlayed by an xyplot line, both of which read off the same Y axis. The problem comes when I try to generate a key. It seems that I can only create either two lines, or two rectangles. I would much prefer to have the barchat series depicted by a rectangle, and the xyplot series by a line. Is there a way to do this? Your help

I am using R 2.3.0, Is there a way to get prediction intervals using predict.gls? Any ideas would be appreciated. thanks, Spencer On 11/2/06, Frank McCown <fmccown@cs.odu.edu> wrote: > > I was wondering if anyone knows who should be contacted to add to the R > user-contributed documentation at > > http://www.r-project.org/other-docs.html > > There doesn't

I was wondering if there was any way to completely remove the borders around each bar when using the barplot function. I understand how to change the color of the border (border="white"), but I need the border to be invisible so I can plot many skinny bars right next to each other with only the bar's color visible.

Hey there, I want to plot 5 parabola functions, which happen to be f(x) = 0.25x? + 6,47x -32.6 g(x)=0.99x? -6x -195 j(x)= 0.77x? +14x -495 k(x)=0.001x? + 65x -785 l(x) = 0.9x? -2x -636 in the same graph. Sadly I even do not really understand how to plot just one graph... I found this code in the Internet, which plots a cos-function: >x <- seq( -10, 10, length = 1000) >plot(x,
