generalizing expand.table: table -> data.frame
In http://tolstoy.newcastle.edu.au/R/e2/help/06/10/3064.html a method was given for converting a frequency table to an expanded data frame representing each observation as a set of factors. A slightly modified version was later included in the NCStats package, only on http://rforge.net/ (and it has too many dependencies to be useful). I've tried to make it more general, allowing an input da...

size of graphs when using multiple figures by row
Hi all, I have a basic question concerning graphs in R. I?m using the par() function and I?m working with multiple figures by row (mfrow) but my the hight of my figures become compressed. I have 4 rows and 2 columns (because I want to plot 8 histograms (freq = FALSE ) on it. I know I can adapt my margins with for example ?oma? and ?mai? but I don?t know how to choose the size of the figure? I read something about pin. That this should go about ?the current plot dimensions, (width, height), in inches. But I don?t know which values I should use. Because...

Fast R implementation of Gini mean difference
I have written the following function to calculate the weighted mean difference for univariate data (see http://www.xycoon.com/gini_mean_difference.htm for a related formula). Unsurprisingly, the function is slow (compared to sd or mad) for long vectors. I wonder if there's a way to make the function faster, short of creating an external C function. Thanks very much for your advice. gmd

Problems with enabling hypervisor C and P-state control
Hi, Is there any documentation on enabling hypervisor support for both C and P-state control? On xen-unstable and linux-2.6.18-xen.hg, if I enable cpuidle=1 on the xen command line and then run xenpm, I will get output for C-states (shown below) but it complains that "Xen cpufreq is not enabled!" cpu id : 0 total C-states : 2 idle time(ms) : 73264 C0 : transition [00000000000000000000] residency [00000000000000000000 ms] C1 : transition [00000000000000025505]...

data manipulation for plotting
Hi, i'd like to plot some data that I have with the value on the x axis and freq on the y axis. So, I need to calculate the freq a value is seen within my data vector for example, say i have a vector of data data=c(1,1,1,4,5,5,6) I want values<-c(1,4,5,6) freq<-c(3,1,2,1) in order to enable me to plot this. Sorry, i'm new to R. What is s...

hist: rel.freqs
In R0.61, In hist(), should the line rel.freqs <- counts/(sum(x) * diff(breaks)) computing the relative frequencies or height of the rectangles in a histogram not be rel.freqs <- counts/(sum(counts) * diff(breaks)) instead, or do I misunderstand something? Thanks, Philippe -- -------------------------------------------------------...

hist() and density
There were some questions about hist() a couple of days ago which triggered this post. My question/suggestion is about the y-axis in hist. There are reasons to prefer making the y-axis density=relative frequency/bin width. One reason is that the height of the plot does not depend on the bin width; another is that if your histogram is in density then you can easily superimpose a smooth theoretical pdf on top--they will be on the same scale. (BTW the best intro stats book--Freedman et al--only shows stu...

bowed linear approximations
...Interpolating the data only makes sense if there's no random component to the response (mag in your data). Otherwise, it makes more sense to get "predictions" from a statistical model that has an explicit error component for the response. In your case, a simple quadratic model in log(freq) seems to fit the data reasonably well. To see what I mean, try plot(log(freq), mag) mod <- lm(mag ~ poly(log(freq), 2)) summary(mod) points(log(freq), fitted(mod), pch=16) lines(spline(log(freq), fitted(mod))) Some basic regression diagnostics suggest that we can do better by taking the log...

Problem in performing goodness of fit test in R.
I am trying to perform goodness of fit test using R. I am using this website http://wiener.math.csi.cuny.edu/Statistics/R/simpleR/stat013.html for help. However, I am unable to carry out the test successfully. My code follows. It is taken from the website just mentioned. freq=c(22,21,22,27,22,36) # frequencies obtained after rolling the dice 150 times. prob=c(1,1,1,1,1,1)/6 # specify expected frequency for each category. chisq.test(freq,p=prob) # I do not know what this line means. I just followed instructions on the website. The erorr I receive is "erorr in chisq....
