Hello together, I am an absolute noob in R and therefore I need help urgently. I have received a script from my tutor with plot functions in it. However, I can' manage to adapt these plots. The hole script is as follows: setwd("E:/") ##### (1) Read data ### dat <- read.table("Komfort_Tatsaechliche_ID_Versuchsreihe_1.txt", header=TRUE, sep="\t",

Dear users, My problem concerns save() within a for loop. Here is my code: for (i in 1:4) { temp <- data.frame(a=(i+1):(i+10), b=LETTERS[(i+1):(i+10)]) filename <- paste("file", i, sep="") assign(filename, temp) save(filename, file=paste(filename, ".rda", sep="")) } As you can see, save() doesn't work as I would like: (1) the object

Hi everybody, Question: why are my dataframe and numeric variables a character? I read an excel file via readxl but my dataframe is a character, and numeric variables, eg "yi", are also a character. My excelfile is in English numeric Sometimes the dataframe was indeed a dataframe, but I do not know why it did sometimes. Thank you in advance, Roberto PS I used "guess". The

Dear users, I have looked on different sources and found different functions to prompt the user to provide input. However, I couldn't find one that does exactly what I'm looking for. select.list() and menu() are nice because a graphic window appears to prompt the user. However, the user can only choose from a predefined list of choices. readline() and scan() are more free in the

Dear users, I would like all the ticks on a boxplot (x and y) to be labeled I have checked all the par() arguments but couldn't find what I'm looking for Here is an example to show it: df <- structure(list(SPECSHOR = structure(c(1L, 1L, 1L, 3L, 3L, 3L, 3L, 3L, 4L, 4L), .Label = c("cotau", "dibic", "eqgre", "gicam"), class =

It looks from str(SA) that Response IPS1 is a data.frame of class "anova", which probably cannot be coerced to vector. Maybe you can use unlist() instead of as.vector() Or something like SA[["Response IPS1"]]["as.factor(WSD)",] ## to select the first row only, even maybe with unlist() Without a better REPRODUCIBLE example, I cannot tell more (maybe some others

Dear users, I would like to process all the lists from all *.rda files that I have in one folder. Up to now, I can load all the *.rda files without any problem. The problem is when I want to access the list saved within each *.rda file (only one list per rda file). Here is my code: fpath <- "D:/R" listnames <- list.files(path=fpath, pattern=glob2rx("*.rda"),

Dear R users, I would like to compare two dataframes, actually their categorical variables (as factors) only (there are 12, from column 1 to 12). The reason I do that is that I got 2 datasets from two different methods and I would like to be sure that each method used the same data (3D images) to extract 2 different sets of 3D parameters. Is it clear so far? So I thought about using

Dear users, I'm trying to get a dot plot but always end up with a boxplot. Can someone please tell me what I am doing wrong? df <- structure(list(FACETTE = structure(c(1L, 1L, 1L, 1L, 2L, 2L, + 2L, 2L), .Label = c("base", "tip"), class = "factor"), Sq = c(274836, + 0.74182, 0.709205, 0.984552, 279869, 255712, 26566, 301464)), .Names = c("FACETTE",

Hello everyone, I have versions 2.7.2 and 2.10.1 installed on a machine that has no access to internet. In 2.7.2 I can use ? to get help on functions, which in 2.10.1 that does not work, all I see is "starting httpd help server...done" and then nothing. Have I downloaded 2.10.1 incorrectly (=forgot to tick some box for local help file repository) or is the internet help now the

Hey all, I am writing a function in which I will have a matrix of 4 columns and a variable amount of rows. The first to columns will always contain be of the Character type, the third and fourth columns can be a variation of data types, usually characters and integers, but sometimes lists or matrices. At one point the code makes, for each row, a copy of that row, then it makes some adjustments

Please excuse me. > Hello > I have a data array with soil variables (caperf), in which the variable "clay" is factor (as I see entering str(caperf)) .

Dear users, I've noticed some time ago that some of the packages I use (especially doBy) could not run (yet) on R 2.11. So I kept on using R 2.10. But I think it should be fine by now. So my question is how do I check whether a package is compatible with the last version of R? How can I check whether it works perfectly or whether there are still some bugs to be fixed? I could ask the

Hi, I have tried looking at the archives but havent found any answer that works till now (Sorry if i have missed anything) I am a newbie to R and i am trying to carry out hierarchical clustering using hclust -> as.dendrogram and then plotting the results as a dendrogram using the plot function plot(object). My question is : In the function "plot", can one decrease the leaf label

Dear helpers, I've looked in the help files (maybe not very thoroughly but I looked) and I couldn't find a straightforward way to permanently set the working directory (where I save and read files). Each time I startup R the working dir is automatically "C:/R/bin" [using:getwd()], and I know I can change it using setwd [for example setwd("C:/R/DATA"), but it's only

Dear users, From the recent discussion, I've wondered whether a text editor would be useful. However, I couldn't find a good explanation of what it is used for. For now, under Windows XP, I use the standard R Editor to write and run scripts. What can I do more with a text editor? It is worth using it? Thanks in advance for your advice. Regards, Ivan

Greetings, I am a very novice user with R, and in the course of running a linking procedure : P.old<- function (a, c, b, xi){ #a contains a parameters #c contains c parameters #b contains b parameters #xi is a one column vector containing quadrature points for xi(=theta-gamma)for one item tmp <- a*(xi-b)

Dear R users, I'm still a beginner and I'm wondering whether S3 or S4 methods really differ for my use. I understand more or less the distinction between the 2 classes from the documentation I've read but the big question is: _*does it make a difference in practice**?*_ Up to now, I've worked without noticing anything, but it might be important to differentiate and to know

Dear group, I am trying to write functions, but as a beginner, everything is not so obvious. Let's say I want the results in a list of elemts like this : tot1, tot2, etc Here is a function: toto <- function(x,y) { for(i in x:y){ paste(c("tot",i),collapse="")<-(i*2) } } If I type this : >toto(1,5) I get this message error: Error in paste(c("tot",
