HI, Sorry Carl, I received your message in my spam folder. Sarah proposed me a good example of code.

Hi, I try to build a loop difficultly. I have in a folder called Matrices several files (.csv) called Mat2002273, Mat2002274 to Mat2002361. I want to calculate for each file the mean of the column called Pixelvalues. I try this code but as result, I have this message: Mat2002273 not found

HI, This code is part of a code I used to do a linear regression: >points(var1~var2,data=Regress,pch=21,bg="grey") >reg11<-lm(var1~var2,data=Regress) >abline(lm(var1~var2,data=Regress),lty=2,lwd=2,col="grey") >legend("topleft",legend= >c("NDII from composite", >"y= 0.0007x - 0.1156",expression(paste(r^2 ==

Hi everybody, I try to do an exponential model with decreasing. In my data, there is no data missing but there negative values. I adapted this following code whose the origin code comes from in this forum: Regress<-read.table("C:\\Users\\Regression.csv",sep=";",dec=",",header=TRUE) Regress f <- function(x,a,b) {a * exp(b * x)} x<-Regress$EWT

Hi, I created a figure with R and I want to save it in .pdf. I used this code: > pdf("res.pca.pdf",width=10,height=8) > library(FactoMineR) > res.pca<-PCA(acp) > res.pca > dev.off() When I go in my folder, I find an empty file ( 0 Ko). Do you know where is the problem. Thank you in advance -- View this message in context:

Hi, Instead to put colour in my histogram, I want to put symbols like lines, dots etc. Do you know the function that does it?

Hi I want to overlay my raster and its boundary which is a shapefile. When I used thise code separately, all is ok: # Open raster >Image<-read.table("C:\\Users\\Documents\\Nouveau\\Frequence.txt",sep="",dec=",",header=TRUE) >testo<-rasterFromXYZ(Image) >plot(testo) >testo2 <- aggregate(testo,fact=10, fun=mean) >plot(testo2) # open

Hi all R users I did a logistic regression with my binary variable Y (0/1) and 2 explanatory variables. Now I try to draw my nomogram with predictive value. I visited the help of R but I have problem to understand well the example. When I use glm fonction, I have a problem, thus I use lrm. My code is: modele<-lrm(Y~L+P,data=donnee) fun<- function(x) plogis(x-modele$coef[1]+modele$coef[2])

Hi all, I am using ggplot2 and continuing to find it very useful and pretty. However, I am trying to create some graphics for publication that would be included in an MS Word document (not my choice!) in Windows Vista. The problem is that I want to use stat_smooth() to add an fitted linear model line along with its 95% confidence band, but I cannot seem to get the confidence band in a format

Hi, I wanted to plot 2 lines on a single graph. Each graph has one axis that can be common. The code that I'm using is: ------------------------------------------------------- par(mfrow=c(1, 1)) x1 <- c(2, 4, 6, 8, 10, 12) x2 <- c(10, 20, 30, 40, 50, 60) y1 <- c(10,12,15,22,34,21) y2 <- c(40, 130, 150, 145, 40, 30) par(las=1, mar=c(4, 4, 2, 4)) plot.new()

Like this? # example using qplot library(ggplot2) meanprice <- tapply(diamonds$price, diamonds$cut, mean);meanprice cut <- factor(levels(diamonds$cut), levels = levels(diamonds$cut)) qplot(cut, meanprice, geom="bar", stat="identity", fill = I("grey50")) dev.new() # create a new graph to compare with qplot # Example using ggplot ggdata <-

Dear R help group I've been working on this plot for a while now and now getting around to the minor adjusments. I would like to be able to put a border and background fill around the legend in this plot. I understand the legend 'bty' should do this have this capablity but not sure how the syntax works in this case ###### initalise library("lattice")

Dear all, being a relative beginner in R, I apologize for posting the second question within two days. So I want a stacked barchart, which should look like the one produced by this code: Tuvalu <- c(9,3,4,0,3,0,0) Singapor <- c(38,0,0,0,12,19,0) Samoa <- c(26,16,2,0,5,2,0) PNG <- c(56,4,0,5,2,0,56) Micronesia <- c(6,0,0,0,0,0,0) graph4 <-

Dear list, Is there a way to reorder the xaxis using lattice. Using the following data, the x-axis is ordered as BP GH MH PF RE RP SF VT but I would like the x-axis to be ordered as PF RP BP GH VT SF RE MH.

Hi, I am newbie user of ggplot and would like some assistance in implementing time series plots. I'd like to know how the tsdiag plot can be made in ggplot? Thanks Harsh Singhal Decisions Systems, Mu Sigma Inc.

Dear R help(ers). I'm an R-learner (about 10 hours now) trying to make a ranked dot plot where the symbols are coded by two variables concurrently. I'm trying to use Deepanyan Sarkar's book 'Lattice' as a guide but get the feeling it is a bit advanced for my level of understanding. I have three questions Q1. Right now I like to know how to get the dual coding working

Dear R helpers I would like to plot vertical reference lines for yearly averages the variable being plotted. In this case there are three years 2002, 2009 and 2010 for a variable Resc_Gt. I've attempted to get the 2002 mean plotting (2.27) using the 'abline' command but no joy. Ideally I would like to be able to compute and plot the means of the three years automatically using a

Dear R users, First just want to say thank you to all for developing such a wonderful software and packages. I need to produce a wind rose plot. Tried with packages circular and plotrix and couldn't quite get what I want. Moved to package ggplot2 and it's going great. However stuck in how to move axis labels. I am using the wind rose from the help to learn how to do what I need (code

Dear R helpers I would like to be able to colour code the y-axis labels on a complex dot plot by a variable known as company (of which there are only two). The code is below and data attached. Thanks MarkM library("lattice") library(latticeExtra) # for mergedTrellisLegendGrob() # set size of the window windows(height=10, width=7,rescale=c("fixed")) ##read the data to a

Dear list,   I made boxplots using ggplot and want to control for x- and yaxis. Using "plot" I can do it by setting cex.axis equally to any size but can't figure out how to do it with ggplot.     ggplot(dat, aes(x = factor(time), y = volume)) + opts(axis.title.x=theme_text(size=8),axis.title.y=theme_text(size=8)) + geom_boxplot() + geom_jitter(aes(colour = id))+labs(x =
