...ible example of your data. The statement "...output does not seem good."  is not very useful. Please explain what you would like the polygon area to look like, and why you don't like the way it came out.  Links to posted images of the chart would help too. <quote> From: Komine <momadou_at_yahoo.fr> Date: Mon, 12 Dec 2011 06:58:56 -0800 (PST) Hi everybody, I have a matrix with 3 columns (Date, MeanArea and SdArea).

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 ==

...ee the contribution of each variable, I use varpart from vegan library. But varpart don?t accepts my 5 explanatory variables, it accept only 4. 1- How must I do to use my 5 explanatory variables? 2- Is it the sum of variance fraction of each variable must be equal to 1. Thanks for your help.

...val equal 1. I tried with zlim=c(1,16) but the result is not good. How do I do it? 2- On the figure, the red color corresponds with the weak values and light red corresponds with the big values. How to invert the color to obtain red color corresponding with the big values. Thanks for your help.

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, I used simple linear regression with the R software and EXCEL on the same data. Although , I find the same R2=0.84, I find different estimated values (intercept and slope). For the R software (slope =0.0009, Intercept = -0.1478), for EXCEL (slope =927.7, Intercept = 154,41). When I use the estimated values from the R software, the results seem bad, however the results of Exel seem correct.

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, After performing a multiple linear regression, I am looking for an R package that can calculate the fraction [a] a partitioning of variation. This fraction measures the proportion of variance of y explained by the explanatory variable x1 (for example) when other variables (x2, x3 ...) are held constant.
