Hi: I have a dataframe containing comma seperated group of words such as milk,bread bread,butter beer,diaper beer,diaper milk,bread beer,diaper I want to output the frequency of occurrence of comma separated words for each row and collapse duplicate rows, to make the output as shown in the following dataframe: milk,bread 2 bread,butter 1 beer,diaper 3 milk,bread 2 Th...

I was looking over some of my specs. I was thinking that the following: @game.should_receive(:name).and_return(''The Battle for Blaze'') @game.should_receive(:people).and_return(5000000) @game.should_receive(:activated).and_return(true) Would it look cleaner if I could do this instead? @game.should_recieve_and_return( :name => ''The Battle for Blaze''

I need to create artificial datasets with specific correlation coefficients (i.e. a dataset that returns r = 0.30, etc.) as examples for a lab I am teaching this summer. Is there a way to do that in R? Thanks.

Hello, I'm looking for a solution for the following problem: I have two vectors V1 <- c("apple","honey","milk","bread","butter") V2 <- c("bread","milk") now, I would like to know for each element in V1 if it's equal to one of the elements in V2 I could do: which(V1 == V2[1] | V1 == V2[2]) but what if I don't know the length of V2 and it's conte...

Hello all - I am sorry if this simple question is addressed in somewhere else. But, I couldn't find it. It's been for about a week using R. . . My problem is: Reading matrix data with "scan" does not seem to allow me to incorporate matrix labels (columns, and rows). If I use read.table, I can import the lables. But, the problem is, I don't know how I make this data as

I feel a bit embarassed by this, but I have not managed to find out how: I have a data frame containing measurements over time for a number of different locations: > str(milk) `data.frame': 845 obs. of 3 variables: $ date : num 1987 1987 1987 1987 1987 ... $ value : num 5 1 2 5 1 1 2 3 2 4 ... $ location: Factor w/ 36 levels "Alta","And?y",..: 1 1 1 1 1 1 1 1 1 1 ...

Hi all, I'm from Brazil. I fit a Tobit model to FLUID MILK CONSUMPTION (DEPENDENT VARIABLE) data using survreg (attached).

...es and all UPSes would have long ago standardized on a single management protocol. The normal thing is that product manufacturers do not want standard commodity products. They want custom, specialized products. That creates customer lock-in. With simple products - like a toaster or a gallon of milk - the consumer thoroughly understands what they are buying - and most of them will not buy a product that significantly differs from the standard. They do not want to buy a toaster that only toasts 1 bakery's bread. With complex technical products consumers are easily fooled, and all the ma...

Hi. I have a box (a net5501 with a Perle serial octal RS-232 card in it) that I want to use as a console server for a bunch of headless computers. I was wondering if there's a trivial app that I can run as the shell that ssh (or telnet) would run, example: #!/bin/bash port=$(echo "$SSH_CONNECT" | cut -d' ' -f4) let -i tty=$port-2000 ttyname=$(printf

Dear R-gurus, I am pretty much new on R. I am trying to to do a repeated analysis of a linear mixed model with R, and I consistently fail... The problem is: Cow is the random factor, treatment is the fixed factor. The dependent variable is milk yield, which is measured several times (repeatedly over time), thus there is another variable which is time (i.e. week). The model would be something like this: milk yield = cow + treatment + time + treatment*time With time as a repeated measure. Would some one be kind enough to guide on how...

I am running R 2.01 on Mac OS 10.3.7. Whenever I save graphs, they are saved as PDF files. Are there any other file formats to which I could save my graphs. I would like to directly export my graphs to MS Word, if possible. Thank you in advance.

...message: Error: couldn't find function "plane3d" I've searched the archives and found no references to such a function. Is (or was) plane3d an actual function or is there just a typo in the scatterplot3d help page? If it is a function, how would I tap into it? Thanks.

...f-topic. Essentially, I need to know if there is any R package which can help me with a deformulation project. Suppose e.g. that you know from a chemical analysis the fat, mineral, vitamin, energy [and so on] content of a certain food product. You also know the ingredients of this product (e.g. milk, lactose, vegetable oil) and you know the chemical composition of each ingredient in terms of fat, minerals, vitamins etc... At this point the question, assuming that the procedure to create the product from the ingredients does not alter the chemical composition of any ingredient, is to de...

...otal basal area per species by the total basal area in the plot. Getting the total basal area in the plot is easy. However, I'm mystified on how to get the total basal area per species. Is there a way to extract and/or sum the total basal area per species? Thank you in advance.

Hi, I'm analyzing a longitudinal data set with 387 cows were observed in 63 days divided into 6 groups, and every 30 days was found to produce milk. Does not aim to model the time using regression. Only compare the groups differ in terms of milk production. There are many missing observations. Because the data are correlated I used the SAS program: proc mixed data=univar method=reml; class RACA GRUPO APELIDO Dias; model Prod =...
