Hi, I have some very noisy, relatively sparse data; a biological response of roughly ~8 subjects at ~8 times points). I've been following the data trend using a lowess line, over-plotted with several values of bandwidth, 'f <- seq(0.3, 0.9, by=0.1)'. At this point, we have no models for these data. I wonder if there is any way under R to assign some sort of confidence interval to

Dear all, I am a newcomer to R. I intend to using R to do stepwise regression and PLS with a data set (a 55x20 matrix, with one dependent and 19 independent variable). Based on the same data set, I have done the same work using SPSS and SAS. However, there is much difference between the results obtained by R and SPSS or SAS. In the case of stepwise, SPSS gave out a model with 4 independent

I don't see the problem with the following... the citations and baseball data work fine, but my simulated data seems to give BTm a headache. What am I missing? --- library(BradleyTerry) library(doBy) ng <- 100 players <- factor( sort( c( "jeff", "mike", "paul", "rich" ) ) ) np <- length( players ) p1 <- factor( c( rep( "jeff", ng )

I don't think there"most". It is normal to have to call the "library" function for each package you need devices to during an R session.

Thanks Jeff. This is a nice way of solving this problem.

So you are saying there are two problems... one that produces a corrupt file from a valid compressed file, and one that segfaults when presented with that corrupt file? Can you please confirm the file name and run md5sum on it and share the result so we can tell when the file problem has been reproduced? -- Sent from my phone. Please excuse my brevity.

It is not generally advisable to get too fancy with stat functions in ggplot... things can easily get more complicated than ggplot is ready to handle when it comes to calculations. It is better to create data that corresponds directly to the graphical representations you are mapping them to. Read [1] for more on this philosophy. [1] H.

I am looking for hints on how to estimate ratings for competitors in an ongoing pairwise competition using R... my particular area of interest being the game of Go, but the idea of identifying ratings (on a continuous scale) rather than relative rankings seems easily generalized to other competitions so I thought someone might be studying something related already. I presume the rating of a

a) you need to read the help pages on the paste function... more likely you are looking for the paste0 function because extra spaces will most likely break the GET request format. b) quotes do not become "stuck" as \" ... that is a visual representation intended to clarify that that quote is not terminating the string but is actually part of it.

When I use rbind() or rbind.data.frame() to add a row to an existing dataframe, it appears that attributes for the column of type "factor" are dropped. See the sample example below to reproduce the problem. Please suggest How I can fix this. Thanks, Sammy a=c("Male", "Male", "Female", "Male") b=c(1,2,3,4) c=c("great", "bad",
