similar to: Vectors of objects...

This is no doubt trivial but after searching the help files and the web, I cannot seem to find it. 1) How do I convert 'hgt' into 'HGT' in R? 2) How should I have used the help facilities to find this? At the end of the day, all I want to do is case insensitive string matching... i.e. 'if ("HGT" == 'hgt') print('this should be true')' I tried

Hi there I have a list that looks like this object1 object1 78 object1 object2 45 object1 object3 34 object1 object4 45 object2 object2 89 object2 object3 32 object2 object4 13 but i want to create a matrix like this in order to use the dist function of R object1 object2 object3 object4 object1 78 45 34 45 object2 45

Hi all, Suppose I want to set the values in a column to the log of the values of another column like so: object$LogDist <- log10(object$Distance) How do I loop through the objects if I have object1, object2, etc to perform this function? object1$LogDist <- log10(object1$Distance) object2$LogDist <- log10(object2$Distance) object3$LogDist <- log10(object3$Distance) I was trying to

Hello, Before I consider purchasing it, can someone comment on the general applicability of John Chambers' book titled "Programming with Data" for R programming. I am currently using R-1.3.1 with the Omega SLanguage and RSMethod packages.

In that case, I can't work out why the first model fails but not the second. I would start looking at "Data" to see what it contains. if: object2 <- polr(Inc ~ Training ,Data,Hess = T,method = "logistic" ) works, the problem may be with the "Adopt" variable.

Dear all, I've started working with R (vs 1041) a few weeks ago, and now I'm having problems with the amount of memory. I'm working on the windows-me, my computer has 128 Mb of memory. I'm using the R under the emacs (ESS-5.1.20) and it is started by the command: Rterm --min-vsize=10M --max-vsize=100M --min-nsize=500k --max-nsize=1M I've been had problems when executing a

hi, i have problem with transactions and multiple databases. Object1 and Object2 are two different models/databases with different connections, when i use only one model: Object1.transaction do object1.value1 = "123456" object1.save do_some_error end it''s ok, error is produced, nothing is commited and database is unchanged. when i use 2 models, described at

Dear R users, I have two simple questions here, and hope someone can help me on this. Thanks in advance. 1. I have a list object lst=list(a1=matrix(rnorm(4),2,2), a2=matrix(rnorm(4),2,2),a3=matrix(rnorm(4),2,2)). Here I only use three elements for illustration, and in fact the length of lst, n, is unknown in advance. I want to define an object for each element of this lst, and the objects have

Dear All I have a program that breaks at the following lines of code: bigfunction = { ... object1 = myfunction(x) object2 = strsplit(object1, ",")[[1]] ... } where myfunction is defined elsewhere outside of bigfunction. The error I get is "error in strsplit() -- object1 not found". However, when I insert browser() into my code so that the above reads, bigfunction = {

Dear r-list folks, I have a problem which has been bugging me for a while now and I was hoping someone out there might be able to help. If I have a user-defined function with an indeterminate number of arguments, using the well-known "..." construct, how can I get the function to return the names of the items which were the arguments of the function as part of the function's

Hi, After manipulate my data I have ended up with 5 different data frames with different number of observations but the same number of variables (columns) An example, if I write str(object1), I see this, data.frame': 47 obs. of 3 variables: $ ORF : Factor w/ 245 levels "YAL038W","YAL054C",..: 10 19 38 39 44 45 50 51 59 60 ... $ mRNA : num 0.891 1.148 1.202

I recently updated all my plugins, and for the fun of it, I added ALL the Rcmdr Plugins to my collection to see what functionality might exist. I started Rcmdr and loaded ALL the available Plugins from to the Rcdmdr Tools menu. To my suprise Rcmdr produced a number of warnings and finally an error. The error suggests that some of the extensions are incompatable with each other because of menu

Hi all, I found the web site for R and decided to install it on my freebsd system; however, I have run into 'permission problems' during execution. I do the standard .configure, make, make check, make install and install into the default location of /usr/local/... but when a normal user attempts to run 'R' I get the following: --- [tulip ~]% R R : Copyright 2001, The R

Dear R users I would like to know if there is a way to create a list or an array (or anything) which grows automatically as more elements are put into it. What I want to find is something equivalent to an ArrayList object of Java language. In Java, I can do the following thing: // Java code ArrayList myArray = new ArrayList(); myArray.add("object1"); myArray.add("object2");

Hi, I'm trying to figure out syntax R function rm() needs to remove all objects starting with same name. For example, if I have object1, object2, object3, i want to do an operation similar to UNIX rm object* Thanks. -- View this message in context: http://r.789695.n4.nabble.com/remove-multiple-objects-starting-with-same-name-tp4418694p4418694.html Sent from the R help mailing list

Greetings, I need to compare the ratios of vector sizes like this: length(object1) / length(object2) I have many vector objects to compare, so I would like to do it in a loop. I created a loop like this: mat1 <- matrix() for (i in 1:6) { for (j in 1:6) { mat1[i,j] <- length( paste("object",i,sep="")) /

Hai, ? I've just upgrade samba on my DC's from 4.10.10 to 4.11.2. Which went fine offcourse ;-) but when i checking my replications i noticed the following. ? If people have problems upgrading, the steps to take are : ( Debian buster, samba upgrade 4.10=> 4.11 van-belle repo. ) # update 4.10 to 4.11 sed 's/410/411/g'? /etc/apt/sources.list.d/van-belle.list apt update apt

Hey, I want to compute means and standard errors as two tables like this: se<-function(x)sqrt(var(x)/length(x)) object1<-as.data.frame.table(tapply(Data[Year=="1999"],na.rm=T,list(Group[Year=="1999"],Season[Year=="1999"]),mean))

Hi all, Appologies for the rather basic IO question but I am rather new to R... Migrated from IDL/Matlab recently. I have a rather simple Fortran control file (sigh...) that I am trying to parse and read using R. My problem is that the file's format is somewhat flexible. Imagine: --- 1> 39 1901 2> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 3> 22 24 26 28 30 32 34 36
