[R] side by side plot of Histogram and densityplot

Using par seems easily put a hist and a density side by side on the same output window. I would like to use some features in histogram from Lattice, but how can I put histogram and densityplot side by side on the same graph? Thank you par(mfrow=c(2,1)) hist(y) plot(density(y)) Jue Wang,

[R] Draw a circle at the end of a line

I have a plot of cumulative distribution function which is a step function, I'd like to put a cycle at the right end of each line to indicate that the value here is not available in this line. How can I do that? Thank you. cdf-function(x){ do.call(rbind,lapply(1:nrow(as.matrix(x)),

[R] Arrange histogram

The data set has a number of variables each of which is classified into two groups. For each variable of each group, I need to create a histogram. All the histograms are to be lined up into a file that looks like group1 group2 Variable 1 Histogram histogram

[R] Estimate in Wilcox_test vs wilcox.exact

Does any one know why wilcox.exact sometimes doesn't agree with wilcox_test on the estimate of the difference of medians in two levels ? Thank you Jue Wang, Biostatistician Contracted Position for Preclinical Research Biostatistics PrO Unlimited (908) 231-3022 Example 1: (wilcox_test gives

[R] The W statistic in wilcox.exact

Does anyone know why wilcox.exact gives W-statistic 6 instead of 12 as indicated below. 12 is the rank sum of group 0 of x, which is the linear statistic computed by wilcox_test. y-c(1,2,3,4,5) x-c(1,1,0,0,0) (a) wilcox.exact wilcox.exact(y~x) Exact Wilcoxon rank sum test data: y by x W =

[R] Wilcoxon Rank test of Package Coin

Hi, I am running the following example which can be found on page 12 of the pdf file of COIN package wt-wilcox_test(pd~age,data=water_transfer,distribution=exact, conf.int=TRUE) wt actually contains the estimate of difference in location and the confidence interval of it. I am just wondering

[R] Confidence interval in the Wilcoxon exact test

Hi, Two functions wilcox.exact and wilcox_test give slightly different confidence intervals of the difference of the medians: for example y-c(0,0,1.081,0.594,0,0.769,0,0.009,0,0,0.798,0.405,0.498,0.946,1.35,1.149,0.528) x-c(rep(1,10),rep(2,7)) aa-wilcox.exact(y~x,conf.int=TRUE)

[R] if then else

What is the correct form to write statement meaning: if (a==1) {b=2; c=3}; else {b=0; c=0}; Thank you Jue Wang, Biostatistician Contracted Position for Preclinical Research Biostatistics PrO Unlimited (908) 231-3022 __ R-help@stat.math.ethz.ch
