ks.test troubles
Hi there! I have two little different data. One is a computer test on people, the other is a paper and pencil test. two boxplots show me that the data is almost the same. So now I'd like to know if I could handle all data as one, by testing with ks.test: ==== > ks.test(el$angststoer, fl$angststoer) Two-sample Kolmogorov-Smirnov test data: el$angststoer and fl$angststoer D =

format a number
Hi there! I have i.e. v = c(0.43554, -0.22343), and so on. Now I'd like to make a format like format(v, digits=2) but without the leading 0, so 0.43554 becomes .44, -0.22343 becomes -.22 How can I do that? runnable example for copy and paste: v = c(0.43554, -0.22343) format(v, digits=2) Thanks, Martin -- Ihr Partner f?r Webdesign, Webapplikationen und Webspace.

Correlation matrix one side with significance
Hi there! In my case, cor(d[1:20]) makes me a good correlation matrix. Now I'd like to have it one sided, means only the left bottom side to be printed (the others are the same) and I'd like to have * where the p-value is lower than 0.05 and ** lower than 0.01. How can I do this? And another thing: Is there a way to output that table as a latex table? Thanks, Martin -- Ihr

mean and sd with number of values?
Hi there, When i do mean(fl[1:20], na.rm=T) sd(fl[1:20], na.rm=T) I get 20 Results, but now I'd like to know from how many numbers my mean and sd are calculated. How to I use the length() for this, or is this possible? Because there are missing values in some, but not in all columns. So there should be a different count of numbers. Thanks, Martin -- Ihr Partner f?r Webdesign,

Compare two correlations matrices
Hi there, When I make two correlations matrices of the same size from a <- cor(el[1:20]) b <- cor(fl[1:20]) how can I compare if this matrices are equal?

factanal and plotting?
Hi there! To make a good choice for the estimation of the number of usefull factors. And I'd like to plot a graph like: http://de.wikipedia.org/wiki/Bild:Parallelanalyse.jpg where I don't need the green line (random values). But with str(factanal(data, factors=10)) I cannot figure out where I can find the values for plotting. Can you please help me in this question? Thanks, Martin
