Hi, I want to plot the residuals of a least-squares regression. plot(lm(y~x), which=1) does this, but it plots the y-axis of my data on the x-axis of the residuals plot. That is, it plots the residual for each y-value in the data. Can I instead use the x-axis of my data as the x-axis of the residuals plot, showing the residual for a given x? Thanks!

Dear all, Given mypi mypi <- c(0.1,0.2,0.2,0.1,0.3,0.4,0.4,0.4,0.4,0.2) I want to create myfreq as follows mypi myfreq 0.1 2 0.2 3 0.2 3 0.1 2 0.3 1 0.4 4 0.4 4 0.4 4 0.4 4 0.2 3 where myfreq is frequency of its corresponding observation. How to do that? Thank you, Regards, A. Kudus Institute for Math Research Univ Putra Malaysia [[alternative HTML version deleted]]

Hey, just came across this article. http://www.eetimes.com/news/latest/showArticle.jhtml;jsessionid=ZLCZZJMVGJYNYQSNDLSCKHA?articleID=201202250 . Many of you would be already aware of this.

Though very less is

Hi, A quick beginner's question. I have two time series, A with daily data, and another B with data at varying frequencies, but mostly annual. Both the series are sorted ascending. I need to merge these two series together in the following way: For any entry of A, the lookup should match with B until we find an entry of B that's larger than A's. For all A[i], i = 1,...,N and B[j],
