I want to use the aggregate function to summarize data by a factor (my field plots), but I want the summary to be the majority level of another factor. For example, given the dataframe: Plot1 big Plot1 big Plot1 small Plot2 big Plot2 small Plot2 small Plot3 small Plot3 small Plot3 small My desired result would be: Plot1 big Plot2 small Plot3 small I

Hi, this is not a new doubt, but is a doubt that I cant find a good response. Look this output: > m.lme <- lme(Yvar~Xvar,random=~1|Plot1/Plot2/Plot3) > anova(m.lme) numDF denDF F-value p-value (Intercept) 1 860 210.2457 <.0001 Xvar 1 2 1.2352 0.3821 > summary(m.lme) Linear mixed-effects model fit by REML Data: NULL AIC BIC

Hi, I just try to draw multiple plots in one page using R, I used par command. For example I have 7 plots, but instead of arranging them in the default way plot1 plot2 plot3 plot4 plot5 plot6 plot7 I want them in this order plot1 plot2 plot3 plot4 plot5 plot6 plot7 Could somebody tell me how to do this, please? Thanks so many. Suyan

I have two dataframes (df) that share a column header ("plot.id"). In the 1st df, "plot.id" records are repeated a variable number of times based on the number of trees monitored within each plot. The 2nd df only has a single record for each "plot.id", and contains a variable named "load" that is collected at the plot-level and is only listed once per plot

Dear List, I'm stuck on what seems like a simple indexing problem, I'd be very grateful to anyone willing to help me out. I queried a dataframe which returns a character vector called "plot". I have another dataframe from which I want to subset or select only those rows that match "plot". I've tried subset, and also the "which" command. plot

This may be asking too much, but I'm wondering if anyone has a solution (even a hack) for creating multiple (overlay) plots in an Sweave file and post-processing the overlays in beamer appropriately. For example, suppose I have a series of figure blocks in my .Rnw file: <<plot1,fig=TRUE>>= [stuff] @ <<plot2,fig=TRUE>>= [stuff] @ <<plot3,fig=TRUE>>=

Hi R people! I am looking for some suggestions writing an if-else function. The idea is to characterize different plots containing counts of variables (here parasites). If a plot has a count equal or higher than 4 for any parasite the function should return a 1 else a 0. Later I can loop the function over all plots. Here I have a little subset of my data: VariablePAR Plot1

Hi R user,I am struggling to figure out on how I can calculate the average from the two tables in R. Any one can help me? really your help would be grateful- I am spending so much time to figure it out. It should not be so hard, I think. I have very big data but I have created a hypothetical data for simplification. for example I have : table 1 table 1: species occurance data

Hello, I am trying to plot age distribution data for a certain condition that runs in families. Below is a simplified view of the dataset, i.e. in this case there are four families, each line corresponding to one individual with age at diagnosis and sex. > famdata family age sex 1 fam1 2.1 f 2 fam1 2.3 f 3 fam1 1.0 m 4 fam2 7.3 f 5 fam2 4.1 f 6 fam2 1.2 f 7

Dear R's (most likely Hadley), I want to build a stacked bar plot where I would like to define which colours will be used for each of the groups. However, I do not seem to find a way to do this, even if I've been looking over many places. I have tried several variations, and my final try was this code, but I still do not manage to get the colours as I pre-define. Any hints about how

Hi, I have a 3-d geology problem. I have an xyz fault data set. I am able to view the data set in R using plot3-d but cannot create a raster from it. I need to create a raster and export so that it can be read in arcscene. Can anybody help? Thanks -- Shane [[alternative HTML version deleted]]

Hi, par(mfrow = c(2,2)) will create a 2x2 window that I can use to plot 4 diferent figures in: [plot1 plot2] [plot3 plot4] But how can do 3 so that the bottom spans the width of the upper two: [plot1 plot1] [p l o t 3] Is this possible in R? -- View this message in context: http://r.789695.n4.nabble.com/multiple-plots-in-single-frame-2-upper-1-lower-tp3679574p3679574.html Sent from the R

Hello, I am trying to help a colleague with an R problem (see below) to whit I can only generate a very inelegant solution. Any advice would be welcome. Thanks, Brian If you have two matrices, say a species by trait matrix (Matrix 1 below) and a plot by species matrix (Matrix 2 below), is there a straightforward way to prune one matrix so that the species list matches those in a

Greetings list, I'm currently in the process of migrating some Matlab code to R. It's going well, but I'm running into trouble with plotting. There are a few questions I have. 1) Is there any way to do a 3D line plot in R? This would be what the Matlab function plot3 does. 2) I would like to create 3 separate plots. With Matlab, this is done by doing ... figure; plot...

Hi there, I need to save a series of lattice plots as a PDF, this is my code so far: windows(height=8,width=6) plot.new() library('grid') lattice.options(layout.heights=list(top.padding=list(x=0.15, units="inches"))) print(plot1, split=c(1,1,2,3), more=TRUE) print(plot2, split=c(1,2,2,3), more=TRUE) print(plot3, split=c(1,3,2,3), more=TRUE) print(plot4, split=c(2,1,2,3),

Hi all, I know that I can for instance draw to plots in one using nf<-layout(matrix(c(1,2),1,2,byrow=FALSE)) Imagine I have 3 files: plot1.jpeg plot2.jpeg plot3.jpeg Anyone knows if I can read them and put on one colum and three rows reading directly from the jpeg file? Many Thanks [[alternative HTML version deleted]]

Hello, I am looking for a workaround of "species empty" plots in a correspondence analysis. I tried to do a community structure analysis with a ca via decorana(), ca() and CAIV(), but none of them allow 0 only-rows. I have species (abs./pres) in columns and sites in rows sp1 sp1 sp3 ... plot1 0 1 1 plot2 0 0 0 plot3 1 0 1 ..... but on some plots no

Hi, I have created a barplot using the following code. a<-c(11,23,15,34,42,31) m<-matrix(a,nrow=2) m[2,]<-(-1)*m[2,] par(mar=c(4,4,4,0)) barplot(m[2,],horiz=T) par(mar=c(4,0,4,2)) barplot(m[1,],horiz=T,col="black") and the plot obtained is shown in "plot1.tiff". I was not willing to see the gap (vertical space) between two graphs. How can I achieve it? Further

Full_Name: Robert Gray Version: 1.4.1 OS: Windows NT 4.0 Submission from: (NULL) (155.52.45.116) I can't seem to get axis tick marks in any color except black (I want to make plots for a slide presentation using a dark background.) Below is a simple example. I have tried this using postscript in the Windows version of R 1.4.1 and a version of R 1.4.0 compiled on a Sun-Solaris system.

Hi Deepayan and everyone, I need to add a common legend to a group of latice graphs, I have tried different ways using viewport and grid.draw without success.
