Dear R users, I have the following two problems, related to the function sub, grep, regexpr and similia. The header of the file(s) I have to import is like this. c("y (m)", "BD (g/cm3)", "PR (Mpa)", "Ks (m/s)", "SP g./g.", "P (m3/m3)", "theta1 (g/g)", "theta2 (g/g)", "AWC (g/g)") To get rid of spaces and

Dear R users, I would like to exactly reproduce a figure like the 1.5 or 1.9 or 4.13 from the book Mixed effects models in S and S-Plus. Not for the sake of it, but because I have my own data I would like to plot in that fashion (no colors) If I write plot(ergoStool) I can get a good informative plot with colors, but I would like to have a B&W one instead. I've played a little with

Dear R-users, my present problem is related to lattice. I would like to put some text in each panel, namely a p-value. I therefore wrote a simple panel function as reported here below. I'm able to write the value in each panel at the maximum value of y for each panel, but this obviously overlay the text to the points. What I'm looking for is to write the text always in the same

Dear R-Users, I'm currently studying the book Statistical model in S by Chambers J.M and Hastie T.J.. At page n 3 there's a plot showing the means of a variable at each of the levels of the factors of an experiment. I hope to be able to reproduce it here by ASCII art.

Hi R users, I'm here trying to understand correlated residuals in nonlinear estimation. I'm reading/studying the book Bates, D. M. and D. G. Watts, (1988), /Nonlinear regression analysis and its applications/, Wiley, NY. pages 92-94, trying to reproduce the figures and to find out the code in R to perform the necessary calculations. I also consulted Pinheiro and Bates, but without

Dear R users, today I've got the following problem. Here you are a dataframe as example. There are some SAMPLES for which a CONCentration was recorded through TIME. The time during which the concentration was recorded is not always the same, 10 points for Sample A, 7 points for Sample B and 11 for sample C Also the initial concentration was not the same for the three samples. I would like

Dear R-users, consider the two following outputs, ## 1 and ## 2 \begin{Scode}{Setup, echo = FALSE, print = FALSE, eval = TRUE} with(expand.grid(Fact1 = 1:3, Fact2 = 1:40), table(Fact1, Fact2)) ## 1 xtable(with(expand.grid(Fact1 = 1:3, Fact2 = 1:40), table(Fact1, Fact2))) ## 2 \end{Scode} The first line with(expand.grid(Fact1 = 1:3, Fact2 = 1:40), table(Fact1, Fact2))

Hi there, this is my first post to the list. I'm a newcomer to the linux world. I started using it on a regular basis on May and I must say I'm quite comfortable with it, even if I have to re-learn a lot of things. But this is not a problem, I will improve my knowledge with time. My main problem now is that I bought myself a new computer (described at the end of this e-mail) and I was

Dear R-users, I have the following problem In a lab experiment I have to mix three solutions to get different concentrations of various molecules in a cuvette I've used R to calculate the necessary ?liters for each of the level of the experiment and I must confess that it is more useful and easier to achieve the results than using spreadsheets. But there's a problem. Imagine that

Dear R-users, the problem I'm facing today is to write a multicolor main title in a plot. I would like to have 3/4 colors to help people in the audience to visually realize what is what in a 4x2 plot array On top of each plot I would like to have two lines. The 1st line will indicate what is plotted The 2nd line will indicate a a reference Graphically speaking I would like a result similar

Dear R-users, after seeking for help in R-search I did not find any hint on my particular problem. Countless help on "true" overlay, but nothing on this. Please consider the following: par(mfrow = c(2, 1)) T <- seq(0, 20, by = 0.01) ## PLOT 1 plot(T, 30*exp(-0.65*T), type = "l" ) points(T, 30*exp(-0.26 * T), type = "l", lty = "F8") points(T,

Dear R users, my problem today deals with my ignorance on regular expressions. a matter I recently discovered. Consider the following foo <- c("V_7_101110_V", "V_7_101110_V", "V_9_101110_V", "V_9_101110_V", "V_9_s101110_V", "V_9_101110_V", "V_9_101110_V", "V_11_101110_V", "V_11_101110_V",

Hi all, I'm trying to work out the following problem, but I can't imagine how. I have the following (much reduced & oversimplified) dataset My.df <- cbind.data.frame(PPM=c(15.78, 15.81, 15.87, 15.83, 15.81, 15.84, 15.91, 15.90, 15.83, 15.81, 15.93, 15.83, 15.70, 15.92, 15.76, 15.81, 15.91, 15.75, 15.84, 15.86, 15.82, 15.79,

Dear R-helpers, the problem I'm facing today is to convince lattice to paint some areas in gray. The areas I would like to have in gray, are confidence bands I've googled around in the mailing list archives and eventually find some clues. This link is my starting point http://tolstoy.newcastle.edu.au/R/e2/help/07/04/15595.html I'm reproducing here the code for your convenience est

ciao, ho aperto un file in R di classe data frame di 15000 righe e 29 colonne. Nella console però sono visualizzate solo la prima e l'ultima colonna e le ultime 8000 righe circa. E' possibile una visualizzazione completa? Grazie Sabrina [[alternative HTML version deleted]]

Deae R helpers, the problem I'm facing today is related to the manipulation of a string. The string is coming from a a porosimeter, whose control is under a complicate set-up of two computers One (running on DOS) is controlling directly the hardware, while the other (running on win XP) which process the data is connected to the first one via serial. I get the data from this last computer.

Hi all, I would like to add to each panel of a bwplot a coloured central band, centered on the mean of the values, being its width +- 2% of the mean itself. I know how to add lines, i.e. something like bwplot(X ~ Y|FACTOR data=my.df, panel= function(x, y){ panel.bwplot(x, y) panel.abline(v = mean(x, na.rm = T) - mean(x, na.rm = T) * 0.02 panel.abline(v =
