Hi there, I'm trying to remove multiple columns by name from a data.frame. As a result I need to get back the modified data.frame without the removed columns. My columns I want to delete are listed in a vector called "delete". data <- read.csv2("data.csv") delete <- c("col1", "col2", "col3") newData <- subset(data, select =

Hi, I'm working with a data.frame containing values between 0 and 22000. Most of the values are actually between 0 and 50 and the high ones are outliers. I want to generate a boxplot and since the outliers are extremely high, I need to scale the y scale logarithmically. Otherwise one wouldn't really see the boxes of the boxplot. boxplot(dat, log="y", ylim=c(0,

Hello. I wonder if anyone can help me with this. I'm performing cluster analysis by using hclust in stats package. My data are contained in a data frame with 10 columns, named "drops". Firs I create a distance matrix using dist: distanxe <- dist(drops) Then I perform cluster analysis via hclust: clusters <- hclust(distanze) At this point I want to view the tree

Hi, is there a way to receive a total summary of a numerical matrix? I'm trying to get a total overview of numerical matrix.

Thanks in advance, -- Anne Skoeries

Hi everyone, anybody’s got an idea why the following script doesn’t produce batch-histograms? I’m using Windows XP and R 2.5.1. Here’s the script: matrix<-read.csv("C:\\Stadtwerke_mit_Umlage.csv", header=TRUE,sep=";",dec=".") Stadtwerke<-colnames(matrix) Bereich_blau<-66.67 Schleifen<-dim(matrix)[2]

Hi, is it possible to put a summary of an rpart-Object into a tktext-window? Here is what I'm trying to do: fit <- rpart(Kyphosis ~ Age + Number + Start, data=kyphosis) tt <- tktoplevel() tex <- tktext(tt) tkpack(tex) tkinsert(tex, "end", summary(fit)) But since the summary of an object is a list, I always get back the following error-message: cannot handle object of

Hello, I have the TCl/Tk command "tkmessageBox(titel="",message="x",icon="question",type="okcancel")" in my R script. Now I want to perform some operation in relation to the user's choice, something like "if (okpressed) xxx else yyy" What values does this command give and how are they used?

Hello, how can I get a variable driven summary of one column of my data.frame? Usually I would do > summary(data$columnname) to get a summary of column named "columnname" of my data.frame named "data". In my case the columnname is not static but can be set dynamically. So I save the chosen columname in something like variable <- "columnname" but how can I

Hi there, a text Window is supposed to map the shortcuts for copying and pasting (<Ctrl-C>, <Ctrl-V>) automatically. I'm working under Mac OS X and my text window doesn't really map these functions automatically - it works fine under Windows. Is there an easy way to map copy&paste functions to a text window under Mac OS X? This is what I'm doing with my text

Dear R-help list, I am working on an optimization with R by evaluating a likelihood function that contains lots of Gamma calculations (BGNBD: Hardie Fader Lee 2005 Management Science). Since I am forced to implement lower bounds for the four parameters included in the model, I chose the optim() function mith L-BFGS-B as method. But the likelihood often returns inf-values which L-BFGS-B

Hi all, I have a problem in including my plot in a loop. Here is a simple example for one plot: # Plot simple graph with super- and subscript a<-c(1,2,3,4) b<-c(1,2,3,4) plot(x=a,y=b, ylab=expression(paste("Apple"["P"])), xlab=expression(paste("Banana"^"th")),

Liebe Liste, bin noch absoluter R-Anf?nger und trotz flei?igen Lesens der Dokumentation noch nicht zur L?sung des folgenden Problems vorgedrungen. Die Werte einer 2D-Matrix sollen in einem einzigen 2D-Plot dargestellt werden, in dem jeweils f?r die Werte einer Zeile ein Graph aus mit Linien verbundenen Punkten gezeichnet wird. Die Matrix besitzt zw?lf Spalten, die x-Achse soll einfach mit 1:12

It seems there have been some changes to ActiveRecord between Rails 1.1.0 RC and 1.10 Final that cause Globalize to fail; 1.10 RC was working fine. When retrieving records from the DB only the base language version is fetched, even when the locale has been set differently. The SQL in the log confirms that Globalize is ignored and a regular find() is performed.

Hi, Sebastian Kanthak of the file_column-Plugin wrote once: "is the photo object inside a local variable or an instance variable (e.g. photo or @photo)? url_for_file_column only works with instance variables, like all other active record form helpers. Could this be the problem?" So I''m using file_column in a partial, e.g. <%= render (:partial => "product",

Hi, Metacity has a keyboard shortcut for activating the window menu. I thinks it defaults to <Alt>Space. Now that compiz has a "proper" window menu it would be nice to have the keyboard shortcut for activating it. Rationale: Being among those who suffer from latent strain injuries from mouse use, I prefer to use the keyboard as much as possible. I can only speak for myself, but
