similar to: readDGE: Error in colnames/length of dimnames not equal to array extent

Hi all... I built a matrix binding vectors with rbind, and have something like this: [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] CLS 3.877328 4.087636 4.72089 4.038361 3.402942 2.786285 2.671222 3.276419 ORD NaN NaN NaN NaN 5.770780 5.901113 11.888054 7.934823 FAM NaN NaN NaN NaN NaN 3.699455 4.551196 2.885390 GEN

Dear R help-list, I am trying to calculate Monmoniers algorithm. I have 3 data sets: coordinates (coord), distance matrix (comdist) and geographical distance matrix (geodist). I consistently get the error " dimnames does not match array extent". However, when I use the function "structure" I get the following results: > str(coord) 'data.frame': 114 obs. of 3

Hello all, I'm trying to use the user-created multinomRob to make some models for my data. While documentation for that function is fine and I think I'm using it correctly, I'm getting the following error when I try to use my lists of variables. data <- read.csv("data.csv", header=FALSE) subj1 <- data.frame(radius=data$V3[9:11], x1=data$V4[9:11], x2=data$V5[9:11],

Hi everyone, I have the following problem: I want to perform a LDA with the function lda(). My data object mat.data is a matrix with dimensions > dim(mat.data) [1] 1228 44 and my grouping vector grp has length 1228: > length(grp) [1] 1228 Every time I call lda(), the following error message occurs: > lda(mat.data,grp) Error in lda.default(x, grouping, ...) : length of dimnames [2]

I'm assuming you are using the corrplot package. If so, your data object does need to be a matrix, not a data frame. Since it's already a data frame, your line of code: as.matrix(as.data.frame(CR1)) doesn't need the as.data.frame function, but more importantly, you didn't assign the result to anything: as.matrix() does not work in place. CR1 <- as.matrix(CR1) Now try. If

Created a new data set with 3 numeric variable to find correlation CR1<- mar%>% as_data_frame%>% select(AGE, OLD_CAR_PURCHASE_YRS, Total.Spend.With.AA) had to convert it to a data frame, code: as.matrix(as.data.frame(CR1)) Now i need to run a correlation plot for these 3 variables: corrplot(CR1, method = "circle") But i am getting this error: Error in

That does clarify for me that you're missing a step: I didn't clearly follow your description at first. corrplot expects a correlation matrix, not your original data. You need to use cor() first. That's pretty clear in the documentation. See for instance the examples: data(mtcars) M <- cor(mtcars) corrplot(M) Sarah On Sat, Mar 17, 2018 at 12:00 PM Shivi Bhatia <shivipmp82 at

Hi Sarah, Thank you for your help. I tried using CR1<-as.matrix(CR1) but gives error Error in corrplot(CR1, method = "circle") : The matrix is not in [-1, 1]!. I am using a corrplot library. Please find the reproducible example: dput(head(CR1,10)) structure(c(26L, 46L, 39L, 38L, 47L, 59L, 56L, 61L, 43L, 60L, 78L, 63L, 2L, 58L, 8L, 1L, 1L, 9L, 11L, 2L, 1037500L, 46747L, 346300L,

I am trying to save an R data.frame as an Excel sheet. I do NOT want the column names saved into row 1. I set colnames=F. However, it still seems that the colnames are saved into row 1. Is this a bug? Or am I coding incorrectly and.or misunderstanding this feature? #example code: sheet = "c:/test2.xls" temp=data.frame(matrix(data=NA,nrow=10,ncol=15)) temp[1,1] =

Have a class for which I would like to provide a "colnames<-.myclass" function so that colnames(myintsance) <- c("a","b","c") can be called. Witold -- Witold Eryk Wolski [[alternative HTML version deleted]]

Hi there, I cannot find a detailed explanation to the following error message: > colnames(matrix(1:10, ncol = 2)) <- c("X", "Y") Error in colnames(matrix(1:10, ncol = 2)) <- c("X", "Y") : target of assignment expands to non-language object However, when I do the following things, the error message disappear: > z <- matrix(1:10, ncol =

Hello, please see below my code for a heatmap. Unfortunately my column names do not completely appear. Can you please send me the appropriate code to visualise them? Many Thanks!

Dear maintainers, I'm reporting a bug in qr.coef that mishandles the colnames of matrix. A minimal reproducible example is as follows: x <- cbind(rep(0, 10), rep(0, 10)) y <- rep(0, 10) q <- qr.default(x) qr.coef(q, y) [1] NA NA If x has colnames, then qr.coef will end up with an error: x <- cbind(x1 = rep(0, 10), x2 = rep(0, 10)) y <- rep(0, 10) q <- qr.default(x)

Seems like you got your input and output mixed up a bit... > From: Jack Tanner > > I want to iterate over a data frame by columns, and as I'm processing > each column I want to know its column name. > > > a <- as.data.frame(list(1,2,3)) > > colnames(a) <- c("a", "b", "c") > > colnames(a) You must have the two lines

hi, I have a conversion table for colnames like this: Probe_ID HUMAN_LLID 1 AF106325_PROBE1 7052 2 NM_019386_PROBE1 7052 3 NM_012907_PROBE1 339 4 AW917796_PROBE1 84196 5 L27651_PROBE1 10864 The Probe_ID contains a list of colnames for another data.frame, say x1. I need to convert such colnames to another ID's system, HUMAN_LLID by using the table.

Hello, I have another stupid question. I hope you can give me a hint how to solve this: I have a list and one element is again a list containing matrices, all of the same dimensions. Now, I'd like to set the dimnames for all matrices: example code: m1 <- matrix(1:25, nrow=5) m2 <- matrix(26:50, nrow=5) # ... there can be much more than two matrices l <- list() l[[1]] <-

HI, I have a file named "s1"(which has 14 rows and 4 columns) which is in csv format. I import and call it "A" the file using: A <- read.csv(file="s1.csv",head=TRUE,sep=",") then I transpose it and call it "B"(which will have 4 rows and 14 columns) using: B=t(A) when I want to make 5 samples from "B" (choosing 10 columns) using:

A dataframe holds 3 vars, each checked true or false (1, 0). Another var holds the grouping, r and s: ### start:example set.seed(20) d <- data.frame(sample(c(0, 1), 20, replace=T), sample(c(0, 1), 20, replace=T), sample(c(0, 1), 20, replace=T)) names(d) <- c("A", "B", "C") e <- rep(c("r", "s"), 10) ### end:example How do I get the
