Hi all, Is it possible to draw line segments in a 3d space plot? I'm interested to draw the errors from an observed value to the regression plane, for a textbook example in an Intro Stats handbook for multiple regression. I used the scatterplot3d package to draw the regression plane. Many thanks, Adrian ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Adrian Dusa (adi@roda.ro) Romanian Social

Hi all, The last e-mails about beginners gave me the courage to post a question; from a beginner's perspective, there are a lot of questions that I'm tempted to ask. But I'm trying to find the answers either in the documentation, either in the about 15 free books I have, either in the help archives (I often found many similar questions posted in the past). Being an (still actual)

Dear list members, I'm relatively new to this list; can anyone tell me how to declare missing values once a dataset has been attached? For example here: VAR1 1 1 2 2 3 1 4 3 5 2 6 1 7 3 8 3 9 1 10 2 11 98 12 2 13 97 14 99 15 NA 16 3 I would like values 97, 98 and 99 to be treated as missing values. I read

Dear list, I spent about two hours searching on the message archive, with no avail. I have a list of people that have to pass an on-line test, but only a fraction of them do it. Moreover, as they input their names, the resulting string do not always match the names I have in my database. I would like to do two things: 1. Match any strings that are 90% the same Example: name1 <- "Harry

Hello The st->zeta pointer isn't freed in the speex_preprocess_state_destroy() function of the preprocess.c file (alloced in line 167). It's in Speex 1.1.4 by the way. I'm trying to make the denoiser work with my application and has got reasonable noise reduction after applying the denoiser. I, however, haven't been able to find any information of what the purpose of

I couldn't find any reference to this in the FAQ, but is it possible to sort a dataframe by multiple columns? I've created some code, similar to the following: nspr.code <- sp.results$sp.code[order( sp.results$sp.code )] nspr.tpa <- sp.results$tpa[order( sp.results$sp.code )] nspr.code <- as.character( levels( nspr.code ) )[nspr.code] nspr.tpa <- as.numeric( levels( nspr.tpa

OK, I'm going nuts here trying to correctly identify null values, specifically when callerID info is not available. FYI, I'm running Asterisk CVS-HEAD-08/17/04-13:08:53, and Bison 1.875a (debian Sid). A snippit of my dialplan looks like this: exten => s,1,SetCIDNum(${CALLERIDNUM}) exten => s,2,NoOp,${CALLERID} exten => s,3,DBGet(temp=idiot/${CALLERIDNUM}) ; Is the person calling

Jean-Marc and others, We are using Speex inside our Video Conferencing application and have some questions about the trade-off of complexity vs bitrate. A little background information is needed: 1. For us the actual bit-rate isn't that big a deal. Speex running at 14kbps or 8 kbps is minor compared to the video traffic running at 128, 256 or 384 kbps. 2. We care a little about

Dear R-helpers, I'm trying to develop a function which specifies all possible expressions that can be formed using a certain number of variables. For example, with three variables A, B and C we can have - presence/absence of A; B and C - presence/absence of combinations of two of them - presence/absence of all three A B C 1 0 2 1 3 0 4 1 5 0 6 1

I'm not sure if this is due to the same problem, but I get the same clipping behavior when trying to use VAD+denoiser on a particular mic+speaker setup that has significant background noise (enough to really foul up the codec should the denoiser be turned off.) Leaving VAD off and transmitting continuously seems to be the only way to avoid this clipping. Another person I regularly

I've got a big data.frame from which I need to extract data based on a variable number of Id's (InfCode). Until now I've been using the following dull solution as I never needed to search for more than 5 codes. Now my needs have increased faster than my R skills did and I need to call my function with about 25 values for x. There has to be a *apply or even simpler solution which

Hi, How can a function in R handle different types of input? I have written a function, which should calculate the slope from several 3-time-point measurements by linear regression 4 three-time-point-measurements: x<-cbind(c(1,2,3,4),c(2,3,4,5),c(3,4,5,6)) time points: time<-c(1,3,9) function for calculating the slope by linear regression: fit<-function(xx,t){slope <-
