similar to: ignore warning messages?

Hi, I'm looking for some way to pick up the numbers which are contained and buried in a long character. For example, outtree.new="(((B:1204.25,E:1204.25):7581.11,F:8785.36):8353.85,C:17139.21);" num.char =

Hi All, I'm wondering whether there is a quick way to know the position of a specific charcater in a long character: for example frg="((D:41.04,I:41.04):45.05,(((E:2.32,((G:0.67,J:0.67):0.44,H:1.11):1.21)" and I would like to know that the 1st, 2nd, 26th, 27th, 28th ... character is "(", is there a quick way to do that? Thanks! Hua

Hi All, I have a problem of putting long titles on a graph: for example, x= seq(1:100) y=seq(1:100) plot(x,y,main="p=0.05:A-B=3,C-D=10,D-E=100,A-F=2,AFR-E=3,ACE-D=1,ADEF-M=0,AED-E=10,DE-F=3,AB-J=4,AC-J=10,ED-F=1,ED-B=4,AF-B=10,CD-S=10,AM-C=4") R seems not able to print the whole title. The title content might be changing and thus I don't know how long it is beforehand. Is there a

I'm interested in testing whether or not a character string is numeric or not as follows: is.na(as.numeric('3')) # returns F is.na(as.numeric('A')) # I'd like this to return T without issuing a warning about NAs introduced by coercion. I guess you could suppress the warning with options(warn=-1), but I was wondering if there's an alternative. Or perhaps an

Hi, All I'm trying to save the workspace as a Check Point for possible future come back. The "save.image" function works if the whole coding is in a main function: rm(list=ls()) t = 1 t = t+1 print(paste("before",t)) # [1] "before 2" save.image("tt.RData") t = t+1 print(paste("after",t)) # [1] "after 3"

Hi there, I'm looking for advice on a R book that's for somewhat advanced user. I've been using R for a while and can do the basic analysis with no problem. My problem is that for many already existing commands, such as gsub, textconnection, list, etc, I don't use them, simply because I don't know their existence! Can someone recommend a good book that I can refer to and can

Hi All, I'm wondering how I can print one large/long character on several lines so that the output will not overflow a page. Setting fill be TRUE or even numbers does not help. An example is below: ipuFile <- file("input.txt", "w") cat("This is a very long character and I want to print it on several lines. This is a very long character and I want to

To creat a series of plots I've constructed the following, however this doesn't work because the colnames being feed into n are embraced by quotes which is stuffing up the plotting function. Is there a way to suppress to quotes? coercion in to a different format?? for (n in colnames(tt[7:36])) { par(ask=T) attach(tt) plot(july~n) ... }

I have a time series from 1933-2005 of precipitation at Fayetteville NC. I get the following error messages when I plot the zoo series. Any help would be appreciated. If you need the data I can dput it or send the csv. I didn't include it here because I didn't want to clog up anybodies email account. I know that this is not reproducible, and I will send along the file if needed.

Hi List, My goal is to force R not to print in scientific notation in the sixth column (rel_diff - for the p-value) of my data frame (not a matrix). I have used the format.pval () and printCoefmat () functions on the data frame. The R script is appended below. This issue is that use of the format.pval () and printCoefmat () functions on the data frame gives me the desired results, but coerces

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

Hello! as(object,"list") and as(object,"matrix") behave quite differently if it comes to their attributes. I define two classes. One of them "contains" a "list" the other a "matrix" setClass("myclass" ,representation(info="character") ,contains="matrix" ) setClass("mylist"

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

Hello, Is there a way to convert a character to a number with out getting a warning? I have a vector that has both numbers and letters in it and I need to convert it to only numbers. At the moment I'm using as.numeric but it is generating a warning when it converts a letter. Is there another function out there that will do what I need or is there a way to turn off the warnings as I

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,

Suppose I have a vector of strings. I'd like to convert this to a vector of numbers if possible. How can I tell if it is possible? as.numeric() will issue a warning if it fails. Do I need to trap this warning? If so, how? In other words, my end goal is a function that takes a vector of strings and returns either a numeric vector or the original vector. Assuming this doesn't already
