similar to: NAs introduced by coercion warning?

I work with Windows and use R version 2.4.1. I am JUST starting to learn this program... I get this warning message 'NAs introduced by coercion' while trying to build a distance matrix (to be analyzed with NMDS later) from a 336 x 100 data matrix. The original matrix has lots of zeros and no missing values, but I don't think this should matter. I searched this forum and people have

Hi, I have a dataframe that I imported from a .txt file by: skogTemp <- read.delim2("Skogaryd_shoot_data.txt", header=TRUE, fill=TRUE) and the data are factors, how can avoid factors from the beginning? Although the file contains both characters and numbers. I tried to convert some of the columns from factor to numeric and as I understood it you can not use only as.numeric but

Hello, I looked in the R-help but could not find an archive addressing the following. I would like to convert a character to numeric after reading a file with RDS extension. After using as.numeric, I checked if it is numeric. It was not converted. Please help. Here is my code >Report <- readRDS(file="RDS/Report.RDS") > Report[1:2,] dive_id date

Hallo, i get a warning message that NAs are introduced by coercion, so my idea is to write a function to see which values are turned into NA For this i need to write a function to go through (loop) the original data and the transformed (with the introduced na) to see which data were transformed to NA. So the return of this function should be a 2*many matrix like structure, eg names:

Readers, I tried to the following commands: plot(y~x,ylab=expression(A[1]~B[2],xlab=expression(C~D)) mtext(expression(A[1]~B[2]),"additional text",side=3,line=1) I receive the text that I want, but the command terminal shows the following response: Warning message: NAs introduced by coercion in: mtext(expression(A[1]~B[2]),"additional text", side = 3, What is my mistake

Warnings are a good thing and can help to find errors in data. But with newer R versions I get more and more warnings which I would like to suppress in defined circumstances. In the manual of as.numeric() is noticed: as.numeric(c("-.1"," 2.7 ","B")) # (-0.1, 2.7, NA) + warning If I know that my data contains characters and if I would like that they will be

Hi, I'm getting the folowing error with sweave. Does someone knows what it means ? Thanks EJ Warning messages: 1: not enough rows for columns in: fun(key = list(text = list(lab = c("v1", "v2")), col = "#000000", 2: not enough rows for columns in: fun(key = list(text = list(lab = c("v1", "v2")), col = "#000000", 3: not enough rows

Hi all, I am trying to package a library in R 1.6.1 (Windoze XP). I have read the document "Writing R extensions" and think I have done things correctly (though apparently not). I have searched the mail archives for help to no avail. When I try to attach the library using, eg > library( libname, lib.loc=path.to.library) I get this message: Warning message: NAs introduced by

Is there a way in R (12.x) to avoid the implicit coercion of factors to integers in the context of subscripts? If this is not possible, is there a way to get at least a warning, if any coercion of this type happens, given that the action of this coercion is almost never what is wanted? Of course, in the rare case that as.integer() is applied explicitly onto a factor, the warning is not needed,

Hi all, The coercion function defined for the ALTREP object will not be called by R when an assignment operation implicitly introduces coercion for a large ALTREP object. For example, If I create a vector of length 10, the ALTREP coercion function seems to work fine. ``` > x <- 1:10 > y <- wrap_altrep(x) > .Internal(inspect(y)) @0x000000001f9271c0 13 INTSXP g0c0 [REF(2)] I am

Hi, I am looking into a way to hook into the R coercion framework to allow me to convert table-like data stored within a COM object into a data.frame. Some of our COM objects have their own table-like data storage, and from R's point of view it's an object (EXTPTRSXP) decoarated with a sepcial symbol so we can easily identify it. COM_Table <- a_method_that_creates_the_object()

Any ideas what is the problem with this code? > N <- 2; c(Sys.Date(), sprintf('N = %d', N)) [1] "2012-01-10" NA Warning message: In as.POSIXlt.Date(x) : NAs introduced by coercion Best regards, Ryszard Ryszard Czerminski AstraZeneca Pharmaceuticals LP 35 Gatehouse Drive Waltham, MA 02451 USA 781-839-4304 ryszard.czerminski@astrazeneca.com

Hi R users I am wondering how I can avoid automatic coercion of my numeric vector elements to character init <- c(age='N', R=as.numeric(0.5), S=as.numeric(0.8)) I have used as.numeric() but it does not seem to work Thank you Lorenzo [[alternative HTML version deleted]]
