Dear R-help subscribers, I have a quite stupid question about using lapply. I have the following function: create.gradient <- function(i){ colorgrad01<-color.scale(seq(0,1,by=0.01), extremes=c("red","blue")) tree1$edge[i,1] -> x tree1$edge[i,2] -> y print(x) print(y) all2[x] -> z all2[y] -> z2 round(z, digits = 2) -> z round(z2, digits = 2) -> z2

Hello R-users, I apologize for my question but I'm a newbie. I want to read a file which columns separator is "\t". At the end of each row there is a "\n" to go to the following line. The three first lines are remarks lines and the fourth contains columns titles ( variables names, ids, dates, calculated values, observed values...) . I do: read.table("myFile",

Hi, I am somewhat new to R so this question may be foolish, but is it possible to add decision trees into a list, array or vector in R? I am trying to build a collection (ensemble) of decision trees. Every time a new instance arrive I need to get the prediction of each decision tree. I have tried to add a decision tree into a variable but without luck. Is a special package needed perhaps? This

Hello Folks, I have 5 columns for thousands of tree records that record whether that tree was alive or dead. I want to recode the columns such that the cell reads "found" when a live tree is first observed, "alive" for when a tree is found alive and is not just found, and "mort" when it was previously alive but is now dead. Given the following: > tree_live

So I have 2 sets of data - a training data set and a test data set. I've been doing the analysis on the training data set and then using predict and feeding the test data through that. There are 114 rows in the training data and 117 in the test data and 1024 columns in both. It's actually the same set of data split into two. The rows are made of 5 different numbers. They do represent

Hi, have anybody positive experience how it is possible get the post output from a rpart-object in a large sweave file or is only the less nicely plot function instead of post possible??? \begin{figure}[htbp] \begin{center} <<fig=true,eps=T>>= post(dtreeEB, title="Tree",digits=getOption("digits") - 0,use.n=TRUE) @ \caption{Tree1} \end{center}

This is a call for comments, regarding what you do expect when copying multible source tree roots leading to the same directory root, using rsync. This problem may be discussed now, because in versions before rsync-2.5.6, the algorithm for removing the so called "duplicated files" was broken. That's why we expect nobody used it anyway in earlier versions - but who knows.. Example:

Hi, the following series adds a --key option in the majority of tools: this makes it possible to pass LUKS credentials programmatically, avoid the need to manually input them, or unsafely pass them via stdin. Thanks, Pino Toscano (2): mltools: create a cmdline_options struct Introduce a --key option in tools that accept keys builder/cmdline.ml | 2 +-

Wherever we had code which did: if (something_bad) { perror (...); exit (EXIT_FAILURE); } replace this with use of the error(3) function: if (something_bad) error (EXIT_FAILURE, errno, ...); The error(3) function is supplied by glibc, or by gnulib on platforms which don't have it, and is much more flexible than perror(3). Since we already use error(3), there seems to be
