I have *** attached *** an RData file containing an R object that is acting strangely. Try this in a fresh workspace. Do not load zoo or any other package. We load the object, zz2, from the attached RData file. It is just the number 1 with the class c("zooreg", "zoo"). Now create an S3 print routine that simply prints an X when given an object of class "zoo". If

I am dealing with very large data frames, artificially created with the following code, that are combined using rbind. a <- rnorm(5000000) b <- rnorm(5000000) c <- rnorm(5000000) d <- rnorm(5000000) first <- data.frame(one=a, two=b, three=c, four=d) second <- data.frame(one=d, two=c, three=b, four=a) rbind(first, second) which results in the following error for each of the

Please help me interpret the following results. The full model (Schwa~Dialect*Prediction*Reduction) was reduced via both update() and step(). The minimal adequate model is: ancova<-lm(Schwa~Dialect+Prediction+Reduction+Dialect:Prediction) Schwa is response variable Dialect is factor, two levels ("QF","SF") Prediction is factor, two levels ("High","Low")

hello I think I've found a bug I don't know if it's a chron bug or a R one. (05/12/05 23:00:00) +1/24 gives (05/12/05 24:00:00) instead of (05/13/05 00:00:00) it looks like the same but it's not because when you get the date of this datetime it says day 12 instead of 13. Please, forward it to the place where this bugs are supposed to be posted. cheers -- View this message

Hi Ya'll I'm trying to install the zoo library... I've downloaded about 5 or 6 of their releases (inc. the latest one), all of them giving me the same syntax error when trying to install... Anyone seen this problem before? its not the "lib" argument that is the problem (ive been installing other packages using this exact format with no problem... just zoo is the problem.

Hello, everyone, There's a problem about zero in R and I really need your help. I have a vector shown as x=c(0.1819711,0.4811463,0.1935151,0.1433675), The sum of this vector is shown as 1 in R, but when I type 1-sum(x), the value is not zero, but -2.220446e-16. I can accept that this value is quite small and could be seen as zero, but there would be a problem when it's not really

Dear All, I encounted in a problem with as.POSIXct() function. > as.POSIXct("2009/03/26 01:00:00 AM" , format="%Y/%m/%d %I:%M:%S %p") [1] NA > as.POSIXct("2009/03/26 02:00:00 PM" , format="%Y/%m/%d %I:%M:%S %p") [1] NA I have tried this in the R version 2.11.1, R version 2.10.1 and R version 2.9.2 .

My debian Synaptic just updated me with winelib 9.58, which I should have been looking out for - because winelib 9.58 totally messes up internet explorer's display of pages with fixed backgrounds. (Repeated images, garbles everything). But winelib 9.44 is Ok, so I need to downgrade. Does anyone know of a repository that has winelib 9.44? Thanks.

  Hi there,   I am beginner in R and I have some basic question. Suppose I run a common procedure such as a t test or cox model like below:   out<-coxph( Surv(tstart,tstop, death1) ~ x1+x1:log(tstop+1) , test1,method=c("breslow"))    Which yields the following result:   Call: coxph(formula = Surv(tstart, tstop, death1) ~ x1 + x1:log(tstop +     1), data = test1, method =

Hello I have a table describing butterfly range traits. It is composed of three columns as below Species name range size (X) latitude of range midpoint (Y) There are 11 kinds of butterflies. Each has its range size, and the latitude of each range midpoint ranges from 9 to 19. I would like to have the average range size of every degree of latitude. For example, the average range

I am attempting to add a calculated column to a data frame. Basically, adding a column called "newcol2" which are the stock closing prices from 1 day to the next. The one little hang up is the name of the column. There seems to be an additional data column name included in the attributes (dimnames?). So when i run HEAD(DATAFRAMENAME) i get the column name = "Open". but

Hello! I am trying to run a GLMM using LME4, and keep getting the warning message: "In mer_finalize(ans) : false convergence (8)" I am quite new to R, and in looking into this thus far, it appears that there are a variety of reasons why this might occur, such as needing to standardize some parameters or if all subjects in one combination of parameters all have the same outcome. I also

Folks: I've got several systems attached to a 2003 domain where we use kerberos to authenticate. When I upgraded a system to the latest greatest samba things stopped working. Just to find where it happened in the different versions of samba I downloaded, built, & ran 3.0.23d to 3.0.25c using the same smb.conf file. Turns out the 2.0.23d and 3.0.24 works but from 3.0.25 on it fails.

Hi, I am using the rcs() function in the Design library to model non-linearity that is not well characterized by an otherwise mechanistic function. I am able to make the model 'available' to others through the excellent nomogram() function and the set of tables that it can create. However, I would like to present the model in an 'expanded' format-- probably what rcspline.restate()

Current dragonegg svn has all of the -fplugin-arg-dragonegg-enable-gcc-optzns bugs for usage with -ffast-math -O3 addressed except for those related to PR2314. Using the -fno-tree-vectorize option, we can evaluate the current state of -fplugin-arg-dragonegg-enable-gcc-optzns with the Polyhedron 2005 benchmarks compared to stock dragonegg and stock gcc 4.5.4. The runtime benchmarks below show that

Hi R- USER, I have been struggling to compute path analysis in R. I installed package "sem" and I tried to run the analysis but could not get a diagram. I have very big data set, here I just copied a sample of my data and I wanted to see how I can do the path analysis and get the patch diagram (with r2 in each path). I have two tables; 1: num. of species - which is the depended

I use by() to generate a summary statistics like so: Lbys <- by(dat[Nidx], dat$LipTest, summary) where Nidx is an index vector with names picking out the columns in the data frame dat. This returns a list of character arrays (see below for str() output) where the columns are named correctly but the rownames are empty strings and the values are strings prepended with the summary
