Dear all! After hours of trying around, I gave up: I have a 2-dimensional array, and I know how to split it into its rows and how to get the mean for every row using 'sapply'. But what I want is to calculate the mean over the first n rows, and then the second n rows, etc., so that I get a vector like: v == mean1(row 1:5), mean2(row6:10),... (trivial, you might say. I find it rather

Hi, there! I finally became a disciple of 'R', after having lost years of my life handling data with a popular, rather wide-spread spreadsheet-software. Now I want to plot the results of many runs of my simulation over time, so that the means +/- Standard error are on the y-axis, and time on the x-axis. I have tried 'boxplot', with timesteps as the grouping variable, but did

Hi, I'm trying to figure out how to properly construct a graph of frequencies of a difference between 2 values, that is | i | - | j |. I'd like to know the best way to store the actual data because of course doing my_vector[i -j] will not work because the index could be negative. I know there's no hash table so what's the best solution, simplicity-wise ? Use a list of pair of

I think I am overlooking a call or concept in R to help me easily and quickly restructure my data.frame:   Sometimes the data I receive looks like: VariableName, Run1, Run2, Run3, Location temp,               15.0,  16.0,  17.0, There   And other times it looks like: VariableName, Run, Location temp,               17.0, There   I would like to use the header information in order to be able to

Hello I am new in R. I am trying to implement Biomod 2 package. However, I have a doubt. I want to calculate the mean and sd of "Testing.data" (ROC and TSS) > # let's print the ROC scores of all selected models > myBiomodModelEval_55["ROC","Testing.data",,,] RUN1 RUN2 RUN3 RUN4 RUN5 RUN6 RUN7 RUN8 RUN9 RUN10 0.938 0.938 0.926 0.931 0.939

I am seeing a very strange situation where doing: make -C dir all does not rebuild anything in dir, even though stuff is stale. This command is what the recursive makefile uses to walk the directory structure. The really strange thing is that: cd dir; make all does rebuild stuff. Does anyone have any idea what is going on here? I thought they were identical. -Chris

> make -d -C dir all >run1 > cd dir; make -d all >../run2 cd .. diff -udb run1 run2 | less But maybe you don't have GNU make, but some Apple (BSD-derived) make which doesn't have the "-d" switch ...

Dear All Sorry for what appears a trivial matter - I'm new to R and am stumbling ahead. I have a table of numerical data (36 rows by 12 columns) such as below: GM1 GM2 GM3 GM4 GM5 ...etc GM12 Run1 1 2 1 2 3 ... Run2 2 1 3 2 1 ... ... Run36 2 1 1 1 1 I would like to plot simple line graphs of some of the runs or

Hi, I have a lattice lot conditioned on two variables. Example code is: library(lattice) x <- data.frame(d=runif(100), f1=sample(c('yes', 'no'),100,replace=TRUE), f2=c(rep('Run1',30),rep('Run2',30),rep('Run3',40))) histogram(~d | f1 + f2, x) In the plot, for a given value of f2, there are two panels, one for 'n'

Documentation on how to put classes and methods in packages with namespace? How should I define my classes and methods in "dynamicGraph"??? (That is - Can some one point me to the documentation on how to put classes and methods in packages with a namespace? ) Currently it is done by the code below. This gives problems, when a workspace with a "dynmaicGraph" is

+ Erik, who implemented DR1579 Originally, I had the warning similar to GCC's warning, but took it out due to not having DR1579 implemented in clang (warning changed in r243594) Erik in r274291 implemented DR1579, although PR27785 didn't mention anything about std::move It looks like what's happening is that Clang and GCC handles the return differently. Clang needs the std::move

Hi, I am trying to plot a 3d scatter plot using the rgl package but am having trouble. I have a matrix containing x, y and z co-ordinates and a fourth element related to a count variable. I would like to plot the points using plot3d with the sizes of the points related to the fourth element in the matrix. Is this possible with plot3d or do I need to use something else? I include a small example

Hello! I am wondering if it's possible to run - in sequence - code that is stored in several R scripts. For example: Script in the file "code1.r" contains the code: a = 3; b = 5; c = a + b Script in the file "code2.r" contains the code: d = 10; e = d - c Script in the file "code3.r" contains the code: result=e/a I understand that I could write those 3 scripts

Yes, we should produce this warning in C++11 mode too. (I could be misrecalling, but I think the rationale for the current behaviour is based on historical GCC behaviour.)

I've got another edition of my simulation replication framework. I'm attaching 2 R files and pasting in the readme. I would especially like to know if I'm doing anything that breaks .Random.seed or other things that R's parallel uses in the environment. In case you don't want to wrestle with attachments, the same files are online in our SVN

Ol?, Please keep this in the list, I'm cc-ing r-help at r-project.org. And yes, I am Portuguese but R-Help is a mailing list in the English language. As for your new question, I believe that you should start a new thread. This is completely different from the question on computing mean and sd. Ask a new question. Font "arial" is a Microsoft font and as far as I know is not

Hello, I am trying to help someone who has carried out an experiment and I'm finding it quite difficult to understand the appropriate model to use & code it. The response is a measurement - the amount of DNA extracted during the experiment. There were 2 factors to be tested - one is the condition under which the experiment took place and the other is the type of DNA to be

I am pretty new to R. So this may be an easy question for most of you. ? I would like to calculate the squared distances of a large set (let's say 20000) of vectors (let's say dimension of 5) to a fixed vector. ? Say I have a data frame MY_VECTORS with 20000 rows and 5 columns, and one 5x1 vector y. I would like to efficiently calculate the squared distances?between each of the 20000

Dear all, I am not fluent in R and am struggling to 1) apply a lm to a weight-size dataset, thus the model has to run separately for each species, each year; 2) extract coefs, r-squared, n, etc. The data look like this: year sps cm w 2009 50 16 22 2009 50 17 42 2009 50 18 45 2009 51 15 45 2009 51 16 53 2009 51 17 73 2010 50 15 22 2010 50 16 41 2010 50 16 21 2010
