Hello everybody, I'm testing the randomForest package in order to do some simulations and I get some trouble with the prediction of new values. The random forest computation is fine but each time I try to predict values with the newly created object, I get an error message. I thought I was because NA values in the dataframe, but I cleaned them and still got the same error. What am I

Hi, I'm using R to plot some data and associated linear models, and I was wondering if there was a parameter to fix the line width in the graphs (for axis, lines, ...) because I explored the associated help pages and could not find it.

Dear list, Here's a little problem I already solved with my own coding style, but I feel there is a more efficient and cleaner way to write it, but had no success finding the "clever" solution. I want to produce a factor from a subset of the combination of two vectors. I have the vectors a et b in a data-frame : > df <- expand.grid(a=c(0, 5, 10, 25, 50), b=c(0, 25, 50,

Hello ! I'm struggling again against lattice graprhics. ;) I'm trying to produce a conditionnal xyplot with two conditionning factors (let's say A and B). I want the levels of those factors (A1, A2, etc) to show in the margins of the lattice plot, not in the strips between the panels. A1 A2 A3 plot11 plot12 plot13 B1 plot21 plot22 plot23 B2 I managed to remove the

Hello, I'm trying to plot a set of 3 dependant variables (y) against 4 predictors (x) in a matrix-like plot, sharing x- an y-axis for all the plot on the same column/line : y1/x1 y1/x2 y1/x3 y1/x4 y2/x1 y2/x2 y2/x3 y2/x4 y3/x1 y3/x2 y3/x3 y3/x4 In fact, this plot is a rectangular selection of the result of pairs(), limited to the relations between x's and y's

Hello I have a vector gd of 279 values of diameter of limpets. Using 'hist(gd, breaks=seq(10,60,5),plot=F)' I can obtain a vector of 10 centers of size-class ($mids). But I'd like to work on a vector of 279 values being the mids (centers of size-classes) corresponding to the respective 279 values in gd. I looked in the different manuals and in archives of list but didn't find

Hello again, First I want to thank all the people who answered my question about line width in graphs. I promise I will learn the 'par' help page by heart for the end of the month ! I now want to trace some ellipses to emphasize groups of data. I found how to trace circles with 'symbols()', but no ellipse. I'm planning on writing my own function based on

Dear list, I'm stuck with a little graphical problem. I'm generating several lattice plots which are printed in a single postcript device opened by > trellis.device(postscript, theme=canonical.theme("postscript", color=F), file="an_phase2_graph.ps", paper="a4", pointsize = 10, onefile=TRUE, horizontal=TRUE) Everything works fine,but some of these

Hello I want to compare the slope (let's say 'b') of a linear model obtained with lm() to a theoretical value (let's say 'th'). To do so, I think I should compute a 't value' using something like : (b - 'th')/standard.deviation(b) and then look at the p-value of this computed t. I don't understand how to do this in a simple way, just using lm()

Hi, a questionaire data-set with more than one row for one Person make me problems. (1) i want create a function which count the used row for the relevant id ! example: id c.row 1 1 1 2 1 3 2 1 2 2 4 1 4 2 4 3 4 4 4 5 (2) i have got a problem to filter & analyse , because the filter criteria is unlucky a row above or under the ratings which i would like to

What is the recommended/optimal way to perform aggregates on data frames with chron objects? Here is an example: >raw.data 1 07/09/01 4000 2 07/09/01 2000 3 07/11/01 1000 4 07/13/01 800 5 07/13/01 700 6 07/16/01 600 7 07/17/01 500 I'm trying to construct a function that would first aggregate the data (second column) by day (grouping by the first column) according to a

Dear members, I'm using R to do some test computation on a set of parameters of a function. This function is included in three for() loops, first one for replications, and the remaining two cycling through possible parameters values, like this : for (k in replicates) { data <- sampling from a population for (i in param1) { for (j in param2) { result <- function(i,

Hi, Some Mitel products, which are CentOS 6.x or 7.x servers based with some telephony services added, are only supported on VMware virtualisation platform, even all if theses CentOS guests are certified on last CentOS/Redhat Virtualization or Microsoft Hyper V platforms. So, at he moment we have three bad choises : - Migrate part of our virtualization services from KVM/libvirt to VMware ; -

Hi everybody, Hope your are not all on holyday because I've got a problem that is going to drive me crazy... I would like to remove some rows from a dataframe. The rows correspond to some specific indexes which I can get by looking at the name in the first column of my dataset. But I manage to get only the opposite of what I really want (function #1) #Function#1:

With the same system configuration (WinNT4 SP6 and 1.7.0), I get such a Dr Watson crash each time I try to use the Change dir... command in the File menu of Rgui.exe. I doesn't seems to happen if I do this immediately after starting R but well if I already did some computation. I don't have any problem by using directly setwd().

Hello, I need to read a vector containing names of different variables from a text file (a unique column). Among them one is called "T". When I use the function read.table with default arguments and when I call the element of the data frame corresponding to name of this variable it returns me the logical value "TRUE" whereas I was expected it to return the character
