Dear all! I have a problem when I use this equation with R. mpr <- 843.75*exp(-1.119*pg) Error in FUN(left, right) : non-numeric argument to binary operator pg 01 02 03 04 05 06 07 08 09-236 10-63T 11 12 13 14 15 16 17-234 18 19 20 23 1592 NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA 1593 NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA

Dear list, Here's a little problem I already solved with my own coding style, but I feel there is a more efficient and cleaner way to write it, but had no success finding the "clever" solution. I want to produce a factor from a subset of the combination of two vectors. I have the vectors a et b in a data-frame : > df <- expand.grid(a=c(0, 5, 10, 25, 50), b=c(0, 25, 50,

Hi, I like the formatting and the appearance of lattice plots. But I have not succeeded in gettting the right format in my plots with the lattice package in one of my applications. In?the code shown below, I start by constructing a general data frame and show my attempts with the lattice package commands. After that, I use the graphics package and show the kind of plot that I want to get. I would

Dear List, Given, y <- matrix(c(0,1,1,1,0,0,0,4,4), ncol = 3, byrow = TRUE) rownames(y) <- c("a","b","c") colnames(y) <- c("1","2","3") y y2 <- y[2:3, ] rownames(y2) <- c("x","z") y2 how can I stop merge(y, y2, all = TRUE, sort = FALSE) squishing the extra rows? Ideally I want the same as: rbind(y,

I haven?t used Samba for over a decade and, from what I remember, I don?t think this is possible. Whenever I search for "two mount points" or "multiple mount points," I get hits for "multiple users," but not for mount points. I have the following directories I want to share through Samba: /share1/DVR /share1/Audio /share2/Video /share2/Backups /share1 is on

Hola tengo una tabla de tipo data.frame "datos" con la siguiente estructura, simplificada en número de niveles por variable, para crear un ejemplo más sencillo: id anio t_8a t_10a t_12a rankf8 rankf10 rankf12 1 1 100 220 220 NA NA NA 2 1 140 350 350 NA NA NA 3 2 55 165 165 NA NA NA 4 2 60 200 200 NA NA NA 5 2 100 NA NA NA NA NA 6 3 NA 350 350 NA NA NA También tengo una matriz,

Maybe a useful addition to the predict functions would be to return the values of the predictor variables. It just (unless there are problems) requires an extra line. I have inserted an example below. "predict.glm" <- function (object, newdata = NULL, type = c("link", "response", "terms"), se.fit = FALSE,

Hello Jeremy, I think you missed a "/" in: mount --bind /share1/DVR /medium/DVR mount --bind /share1/Audio /medium/Audio mount --bind /share2/Video /medium/Video mount --bind /share2/Backups /medium/Backups BR, Matt On Thu, Feb 13, 2020 at 5:15 PM Jeremy Allison via samba < samba at lists.samba.org> wrote: > On Thu, Feb 13, 2020 at 04:45:16PM -0500, Hal Vaughan via samba

Hi, In 1.4.1, I was able to create extra "empty" rows in a dataframe as so: > x <- data.frame(a = letters[1:3], b = 1:3) > x a b 1 a 1 2 b 2 3 c 3 > x[4,] a b NA NA NA > rbind(x, x[4,]) a b 1 a 1 2 b 2 3 c 3 NA NA NA > R.version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6

Dear R friends I wanted a function to make a simple percent table that would be easy for students to use. The goal originally was to have a simple thing people would call like this pctable(rowvar, colvar, data) and the things "rowvar" and "colvar" might be names of variables in data. I wanted to avoid the usage of "with" (as we now see in the table help). Then

Hi, all I have a medium sized data, 6 years. Each observation is a case with a date variable, such as '2004-08-02'. Some of the months didn't occur a case. I want to plot the 6 years data by month, and the Y_axis is the freqency of cases for each month, meaning 12*6=72 bars or points in the figure. I though of a method, 1st, using the months function, then ploting. But I need to

Hey everyone! I am seeing strange behavior with NA in the rownames of dataframes: > a <- data.frame(1:3, row.names = c("r1", NA, "r3")) > cbind(a) X1.3 r1 1 <NA> 2 r3 3 Everything works. The peculiar thing is that when the NA is in the first row, things no longer work as I would have expected: > b <- data.frame(1:3, row.names

Hello !! I have this problem: A matrix on True/False and as many numerical vectors as columns, but of different length. What I 'd like to get is this: set.seed(12) > dat <- as.data.frame(matrix(as.logical(sample(T:F, 30, T)),5,6)) > colnames(dat) <- letters[1:6] > rownames(dat) <- paste(letters[1:5],1:5, sep="") > dat a b c d e f a1

An NA in the rownames of a matrix (or dataframe) causes misalignment when the matrix is printed: R> x <- matrix(1:12, 3,4, dimnames=list(letters[1:3], LETTERS[1:4])) R> rownames(x)[2] <- NA R> x A B C D a 1 4 7 10 <NA> 2 5 8 11 c 3 6 9 12 The bug is in function Rstrlen, in src/main/printutils.c. MatrixRowLabel and MatrixColumnLabel (same file) rely on Rstrlen

Dear fellow R users, I would like to draw a "sunflowerplot" because I have data (decade by month) that plots multiple times on the same x-y co-ordinates. Further I would like to colour each of the points/sunflower leaves on the plot according to the group they belong to (i.e. which type of event each represents within that decade and month). I thought that this would be relatively

Hi, My first post here and new to R so please bear with me (long time programmer though, helping a friend with some scripts). I've noticed a behaviour when using rownames() that I think is odd, wondering if I'm doing something wrong. To illustrate, say I create a very simple matrix (called fred): fred<-matrix(,4,2) It looks like this: [,1] [,2] [1,] NA NA [2,] NA NA

Dear all, I have a grid of 720 columns by 360 rows of global population density values, and hope to convert this to column format using the 'melt' command in the 'reshape' package. I'm not receiving any errors as such, but when the code has finished running, my output looks like this: > head(PopDens.long) Latitude Longitude PopDensity 1 -84.75 V1 0 2

I suspect there may be a bug in base::rbind.data.frame Below there is minimal example of the problem: m <- matrix (1:12, 3) dfm <- data.frame (c = 1 : 3, m = I (m)) str (dfm) m.names <- m rownames (m.names) <- letters [1:3] dfm.names <- data.frame (c = 1 : 3, m = I (m.names)) str (dfm.names) rbind (m, m.names) rbind (m.names, m) rbind (dfm, dfm.names) #not working rbind

Hello everyone, Apologies in advance if you have received this multiple times! On a thread similar to that posted by Don MacQueen (http://www.r-project.org/nocvs/mail/r-help/2002/3455.html): is there any way to nicely format NA's when listed as rownames? When NA's are part of rownames, the alignment is thrown off: > z <- matrix(c(100, 200, 300)) > z [,1] [1,] 100 [2,]
