similar to: documentation for 'open': some clarification?

Is it possible to get the empirical (sandwich) S.E. estimates for the fixed effects in lme () (thus allowing possibly correlated errors within the group)? In SAS you can get it by the 'empirical' option to PROC MIXED. Cheers, Michael -- Na (Michael) Li, Ph.D. Division of Biostatistics A443 Mayo Building, MMC 303 School of Public Health 420 Delaware

I did: ./configure --with-blas='-framework vecLib' --with-lapack --with-aqua make sudo make install sudo make install-aqua Everything seems to be OK (some warnings about multiple definitions of some symbols).

Hi I have a plist t which contains size measurements of individual plants, identified by the field "plate". It contains, among other, a field "year" indicating the year in which the individual was measured and the "height". The number of measurements range from 1 to 4 measurements in different years. My problem is that I would need the LAST measurement. I only

When `length( skewed.probs ) > 200' uniform samples are generated in R-devel. R-3.5.1 behaves as expected. `epsilon` can be a lot bigger than illustrated and still the uniform distribution is produced.

Dear all, I would like to create a number of vectors which contain the the first n elements of an existing vector. For example I have the vectors vnk (200x1) and vro(200x1) and I want to create 200 vectors that contain the 1st till the n_th element of the vectors and thus be able to create a vector s with 200 elements which are the product of all these vectors: i.e s1<-vnk[1]%*%vro[1]

Rd.sty defines \newlength{\middle} which seems to be in conflict with the my latex installation.

With some help from those with expertise on this list, I managed to produce a plot using trellis that looked like I wanted it to look. Now, I need to take the same plot and make the lines on it color, but I want to specify the color for the lines myself. I've managed to make the key use the colors I want. I've managed to make the symbols of the actual plot use the colors I want. But I

in the mean time i am using a checkbox like this : <input type="checkbox" name="var[car]" <%= var.car ? ''checked'' : '''' unless @var == nil %> /> but i am sure there is something better than this in rails like <%= checkbox_tag ''var'', ''car'', :checked => true %> but this is not

As far as I can tell, 'isOpen' cannot return FALSE in the case when 'rw = ""'. If the connection has already been closed by 'close' or some other function, then isOpen will produce an error. The problem is that when isOpen calls 'getConnection', the connection cannot be found and 'getConnection' produces an error. The check to see if it is

Dear R Users, I would like to plot three time series on the same graph, two axis on the left and one axis on the right. The time series that I am graphing on the left do not share a similar scale: one has a range of 1:100 and the other a range of 25000:70000. How can I display the tick marks for both on the left hand side without superimposing them, i.e. one set of tick marks in black right

I noticed the following file descriptor leak when I couldn't remove a package unless I shut down the R session that had loaded and used it. The function that triggered the problem printed the output of a call to parse(). Each time one prints a srcref a connection is opened and not closed. It looks like it happens in as.character.srcref's call to getSrcLines, which has some logic I

In below graph, I would like to add two vertical lines using panel.abline(). ?Is this possible? Thanks, Naresh mydf <- data.frame(hour = rep(6:20, 2), traffic = c(round(dnorm(6:20, 9, 3) * 10000), round(dnorm(6:20, 17, 4) * 10000)), direction = rep(c("inbound", "outbound"), c(15, 15))) vehicles <- data.frame(hour = 6:20, count = c(100, 120, 140, 125, 105, 80, 70, 75,

Hi, I meet a strange trouble writing shapefiles with write.pointShape() from maptools. > write.pointShape(mylines[,5:9], file="Sxtplinshp", mycoordspt) Error in write.pointShape(mylines[, 5:9], file = "Sxtplinshp", mycoordspt) : shapefile names must conform to the 8.3 format It seems that the function request a special shapefile name spelling (conformed to 8.3

Hello, >From the doc, it says: "isOpen returns a logical value, whether the connection is currently open." But actually it seems to die on closed connections: > con <- file() > isOpen(con) [1] TRUE > close(con) > isOpen(con) Error in isOpen(con) : invalid connection Is it expected ?

Hi! I'm wondering if there's a smart way around this: fileName= (some valid file on your system) > fileCon=file(fileName, open="rt") > l<-readLines (fileCon, n= 1) > > isOpen(fileCon) [1] TRUE > close(fileCon) > isOpen(fileCon) Error in isOpen(fileCon) : invalid connection How do you test for a file being closed if isOpen gives you an error

I assume you want the 'v' variable in panel.abline() to be interpreted in the context of your x-axis, which here represents a factor variable. Unless two factor variables have the same

Hello, I have R as a socket server that computes R code sent by some scripts (the clients). These scrips send R code to generate models (SVM). The problem is that first models are generated in less than one second and one hour later, the same models are generated in more than ten seconds (even training with same data). If I restart the server , then it works well (fast). I don't know if I have

Yeah, that's often a possible workaround, but since this connection was opened by readLines() internally, I don't necessarily know which one it is. E.g. I might open multiple

Cran task views seems to be a "once-per-session" process -- the first attempt to access views in a (RGui for Windows) session works, but subsequent attempts fail. There is a noticeably long pause before the failing call returns. Example session with two calls to "available.views" follows, but similar effects have been observed with two calls to "install.views" and
