R-users, I can't tell what's causing the following error.

sorry if my first msg was posted twice. this email system at school sucks. i've looked in the Admin and Main manual and the Intro manual for something that tells me what error messages mean, but haven't found anything. where can i find the meanings of the error messages?

Michael, Thank you for the suggestion. I will take your advice and look more critically at the covariates.

Dear R users, I have a list of numbers such as > n [1] 3000 4000 5000 3000 5000 6000 4000 5000 7000 5000 6000 7000 and i'd like to set up a loop that will keep track of the number of occurences of each of the values that occur in the list, e.g. 3000: 2 4000: 2 5000: 4 I came up with the following: a<- for (i in 1:length(n)) { r<-0 s<-0 t<-0 u<-0 v<-0

hello all, i want to split a list into smaller lists. the list looks like this: CW-W730 CW-W720 CW-W710 CW-W700 CW-W690 CW-W680 CW-W670 CW-W660 CE-W997 CE-W987 CE-W977 CE-W967 CE-W956 CE-W944 CE-W934 CE-W924 7W-W760 7W-W750 7W-96 7W-941 7W-932 7W-923 7W-914 7W-905 7E-W565 7E-W555 7E-W545 7E-W535 7E-W525 7E-906 7E-850 7E-840 ... i want the smaller lists

UseRs, I have a dataframe with 2547 rows and several hundred columns in R 3.1.3. I am trying to run a small logistic regression with a subset of the data. know_fin ~ comp_grp2+age+gender+education+employment+income+ideol+home_lot+home+county > str(knowf3) 'data.frame': 2033 obs. of 18 variables: $ userid : Factor w/ 2542 levels

I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.

Hello useRs, I'm trying to put italics and regular font into a title and am having some trouble. The title I would like is " /Q. marilandica/ Volume ". If I use main=bquote(italic( "Q. marilandica ", " volume")) I get just " Q. marilandica " in italics in the title. If i use main=bquote(italic( "Q. marilandica ,) volume") I get "

greetings, i'm trying plot() from Owen's _The R Guide_ and having trouble with being able to view the result. the Graphics Device 2 draws an image i can only see the top part of and when i try to manipulate the window to see the image, the window then says: "...ure margins too lar..." in large letters. i guess it says something about picture margins too large. i'm not sure

Dear UseRs, I'd like to make the lines that the axes of my plot run on bold. I know "axis(side=1,lwd=3)" will make 0-max value on the axis bold, but I want the whole thing, from corner to corner (actually all the way around) and tick marks and the accompanying values for the ticks bold. In the default values, it's hard to see the plot when I put it into a powerpoint.

hello all, i'm trying to use QPmat, from the popbio package. it appears to be based on solve.QP and is intended for making a population projection matrix. QPmat asks for: nout, A time series of population vectors and C, C constraint matrix, (with two more vectors, b and nonzero). i believe the relevant code from QPmat is: function (nout, C, b, nonzero) { if (!"quadprog" %in%
