I have a data set for different time intervals. The data has three comment lines before data for each time interval. For each time interval there are 500 data points. I want to change the dataset such that I have the following format: t1 t2 t3 ................ 0.00208 0.00417 0.00625 ................. a1 a2 a3 ...................

Hello, I found a couple bugs concerning my favourite Shade/Unshade function. 1) Sometimes the shaded window gets more space than it should and, of course, nobody takes care about it, so everything drawn on this space remains here. If I move a decorated window along, its shadow cummulates quickly to full black here. Unfortunately, I don't know any reliable way how to reproduce this. (But it

Dear friends, I am trying to understand and implement instrumental variables regression using R. I found a small (simple) example here which purportedly illustrates the mechanics (using 2-stage least-squares): http://www.r-bloggers.com/a-simple-instrumental-variables-problem/ Basically, here are the R commands (reproducible example) from that site: # ------ begin R library(AER)

Dear all, Does any one knows why should I get the following error message, when trying to do a simple data.frame??

Hello, For my functions I want to create output similar in appearance to that of what you get when you print a summary of lm model: Residuals: Min 1Q Median 3Q Max -0.209209 -0.043133 0.001793 0.044105 0.234750 Coefficients: Estimate Std. Error t value Pr(>|t|) (Intercept) 0.981762 0.004089 240.103 < 2e-16 *** Factor 1

Hi, Sorry for this one as its pretty basic but I've taken a look for info and couldn't find any... My question is, does the order of main effect terms in a model specification have any impact on the model R fits or not. (in particular when using lm). ie Can A~X+Y+Z lead to different results to A~Z+Y+X, and if so in what circumstances, and how much should I worry about it? I believe

Hi I need to a function that automatically fits a regression to data, using the stepAIC. I've ran the code manually and it works fine. However, when I run the function on the same data, the following error occurs: Problem in regimp(fullsim = simt, fullsim1 = simt1,..: Length of (weights) (variable 4) is 4271 != length of others (4278) I got the function to output the length of the dataset

Dear R-helpers, I'm stuck with a little problem that surely has an easy solution but I can't think of a way to solve it. I'd really appreciate any help you can offer me! I'll provide a small example. Given a dataframe data.txt that looks like this: ID freq Var Var_mean Ratio_mean Var_median Ratio_median Var_sum Ratio_min Var_max Ratio_max Var_min

Dear All: Could you please tell me how I can draw figure formatted like figure 4.18 of MASS (4th) with the attached data set?

I'd like to use linear and quadratic trend analysis in order to find out a change in slope. Basically, I need to solve a similar problem as discussed in http://www.gseis.ucla.edu/courses/ed230bc1/cnotes4/trend1.html My subjects have counted dots: one dot, two dots, etc. up to 9 dots. The reaction time increases with increasing dots. The theory is that 1 up to 3 or 4 points can be counted

Dear R list members, I've turned up a strange discrepancy between results obtained from the lme function in the nlme package in R and results obtained with lme in S-PLUS. I'm using version 3.1-24 of nlme in R 1.4.1 under Windows 2000, and both S-PLUS 2000 and 6.0, again under Windows 2000. I've noticed discrepancies in a couple of instances. Here's one, using data from Bryk

I am trying to decipher, via post hoc test (Tukey), which of my sites differ from eachother. I have 4 sites, 2 sets of In vs Out (MPA) in separate Regions. Therefore my Mixed Effects Model code has 2 fixed effects: CB.lme <- lme(AsinCB~ In_Out*Region, random = (~1| site.trans/Quadrat) , data = Subsampled_props, control = lmeControl(maxIter = 500, msMaxIter = 500, msMaxEval = 500))

Dear R experts, Excuse me if my question will be stupid... I'd like to fit data with x^2 polynomial: d <- read.table(file = "Oleg.dat", head = TRUE) d X T 3720.00 4.113 3715.00 4.123 3710.00 4.132 ... out <- lm(T ~ poly(X, 4), data = d) out Call: lm(formula = T ~ poly(X, 2), data = d) Coefficients: (Intercept) poly(X, 2)1 poly(X, 2)2

I know that windows exe files can be run using Wine, but I have a windows program I would like to run under PCLINOS and the update/patch is in the form of a .com file. Can a file of this type be used for the update/patch in Wine ?

Hello again, I have been working on the Rice Encoder/Decoder now since my first post. However, I can't identify what's wrong with it. I was hoping there might be someone out there interested in answering my questions outside of this forum. I am not very good at programming at all, but I really want to see this project come together with my own work. (i.e. I don't want someone just

Hi: Since icecast2 is still heading to an initial release, there's no official guide for this stuff, but there is a bit of stuff out there. First, lets clarify what you want to do. When you say "CD content", I assume you mean audio CD's. To provide a stream requires two parts - a source or streamer, and a server. The source is equivalent to a radio studio, the server is

Thanks, all, for the pointers. I think I have everything configured properly, but, something is obviously still wrong. I'm using Kerry's guide with these xml files: - Sample icecast.xml - Configuration for Streaming Live Audio I started icecast & ices as directed. I then started xmms and configured the output plugin to be the OSS driver. I'm playing a music cd. This is all on my

NB: Not reply needed (Ben was extremely helpful!) I've just started using R last week and am still scratching my head. I have a data set and want to run a separate regression across each level of a factor (treating each one separately). The data right now is arranged such that the value of the factor along which I want to "split" my data is one column among many. Best way to do
