Hello everyone, I am trying to prune a data frame for partial least squares analysis. I need to delete an entire row if one cell in the row contains a NA. Presently, I am running a loop that is supposed to extract the rows that are full of numbers into a second data frame and skips the rows that contain a single NA value. I want to know if there is a simple way to determine if a row

Hi, How do I use the string content of a string variable to reference a data frame of the same name? I want to do the typical tasks of 1) building a name with a string variable and using the string variable to create a data frame (or any object) whose name is the string value of the variable and 2) pass on a string to a function as a parameter, and then use that string to refer to an existing

Hello everyone, I have a couple of fairly simple questions (I hope) the answers to which I cannot find through the documentation at the moment. 1. I would like to delete the a row from a matrix if a certain elimination criterion is met. I am familiar with x <- x[-7,] (to remove row 7, for example). Are there any other means of removing an entire row? 2. Is there a single command that

Hi, I have managed to format my data into a single datframe consisting of two AsIs response and predictor dataframes in order to supply the plsr command of the pls package for principal components analysis. When I execute the command, however, I get this error: > fiber1 <- plsr(respmat ~ predmat, ncomp=1, data=inputmat,validation="LOO") Error in model.frame.default(formula =

Hello all, It seems that the GeneMeta passage returns NA in the respective row if any gene in the data sets to be synthesised are missing. Do you know of a way to overcome this problem? I tried using the 'impute' package to fill-in the missing values, but R crashes if 'impute' and 'GeneMeta' packages are used together. I have asked a separate question for that. Thanks

Hi, I have written boxplot commands of this form before, but I don''t quite understand why the function call is reporting a syntax error in this instance. All parameters passed to the function are strings. Thanks in advance. Payam > simplevar <- function(wframe,column1,column2) { + tframe <- get(wframe) + x1 <- which(names(wframe)==column1) + x2 <-

I have encountered a more fundamental problem in my data set. I''m using read.csv, and all the data are imported as character. How do I do a string comparison in a line like this: M10[ !sapply(1:10, function(x)666 %in% M10[x,]), ] Alternately, how do I change the class type on a column in a data frame from character to numeric? Thank you very much. Payam [[alternative HTML version

A time series text with a title that seems designed to hide its wide scope is: Forecasting with Exponential Smoothing The State Space Approach Hyndman, R.J., Koehler, A.B., Ord, J.K., Snyder, R.D. Springer 2009. This book is actually an excellent overview of time series theory, ARIMA as well as state space. It is of course, in part, a manual for the forecast and other packages in what has been

With apologies if I missed the answer in the response given to my previous question. How do I extract the name of an object and assign it to a string variable? For example, I have a dataframe named comnoglyc How do I assign this name to a variable dfname such that print(dfname) returns "comnoglyc"? Thank you very much.

Hello everybody, it's a few minutes that i've subscribed in your mailing list. nice to meat all of you. I have samba on redhat 8 as a file server for a couple of "win98" & "winXP"'s.It work's for my XP OS's but I don't know how to join the "win98" 's in. please help me thanks payam.

The following: library(grid) grid.newpage() example(Grid) has the yaxis label partly cut off and the x axis label does not appear at all. Also ?grid.multipanel in that example brings up documentation for grid-internal but this would not seem to be internal if its part of an example. I am using: > R.version.string # Windows XP [1] "R version 2.2.0, 2005-09-20"

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Estimado Javier, adjunto el grafico retocado con GIMP, borre las lineas que sobran en cada panel. Obviamente, no es la idea hacerlo de este modo, sino con R, pues quiero cambiar el color de la recta y hacer varios otros graficos, cuya edicion manual requeriria mucho tiempo. Espero entiendas mejor mi explicacion ahora. Cada una de esas rectas es un

I cannot achieve a multipanel display of several levelplots. Here is part of my code. At first, create the layout: push.viewport(viewport(layout=grid.layout(1, 2))) Then for the left panel: push.viewport(viewport(layout.pos.col=1,layout.pos.row=1)) push.viewport(viewport(width=0.6, height=0.6)) levelplot(z~x*y, grid) pop.viewport() Similar code for the right panel. However, there is always

Dear R-users, I am trying to create a multipanel scatter plot which displays weighted regression lines for each subgroup. I am having diffuculty figuring out how the Trellis multipanel plotting functions work, in general. Does someone know where there are some beginners examples on how to create and use panel.xxx functions in conjunction with the xyplot functions? Back to the matter at hand

Is there a simple way to specify a theme or trellis (lattice) parameters so that, in a multipanel (conditioned) plot, there is no color and in the strips there is no shading? This is the effect achieved on page 124 of Deepayan Sarkar's "Lattice" (figure 7.2). I managed to trick lattice into making a grayscale plot on my interactive display as follows: > graphics.off() >

Dear R-projects users I would like like to ask if there is any way to produce a multipanel plot with the filled.contour function. In the help information of filled contour it is said that this function is restricted to a full page display.

I'm trying to add a set of reference lines to a multipanel xyplot xyplot(y ~ x | Visit, panel = function(x, y, ...){ panel.xyplot(x, y, ...) abline(v = c(0.5, 1)) }) However, the reference lines are different for different visits. For example, for the first 2 visits, I'd like vertical lines at x = 0.5 and 1. For visits 3 and four, I'd like vertical lines at x = 1 and 1.5. I can

Derar Rxperts, I have a strange situation.. I see curly brackets around "strip.levels" in multipanel strips while using lattice::xyplot. .How do I get rid of the curly brackets? For some reason, I am not able to reproduce the problem using an example below... Any suggestions are highly welcome! Thanks, Santosh q <-

Hi, I'm making a multipanel lattice densityplot figure with 2 factors (3 and 20 classes in each factor) with the following statement (the type="percent" is there to prevent plotting the actual points which detract from the figure - is there another way of doing this?): densityplot(~End-Begin | Type * Chromosome, data=Mon, layout=c(5,12), xlab="Element

I want to create a simple plot containing three levelplots with one colorbar. I used the "Three levelplots" code below, but the third levelplot is drawn smaller than the first two. However, if I try the "Two levelplots" code below it works well. Can anybody tell me how could I draw three levelplots (of the same size) with one colorbar. Thanks in advance, Joaquin ### Three
