Hi! Here is some output from an str command: > str(CO2) Classes ‘nfnGroupedData’, ‘nfGroupedData’, ‘groupedData’ and 'data.frame': 84 obs. of 5 variables: $ Plant : Ord.factor w/ 12 levels "Qn1"<"Qn2"<"Qn3"<..: 1 1 1 1 1 1 1 2 2 2 ... $ Type : Factor w/ 2 levels "Quebec","Mississippi": 1 1 1 1 1 1 1 1 1 1 ... $

Hi, I just started a new course this semester on R, I never used it in my life and i'm stuck on these questions from 3 days, it would be really nice if someone could explain me the answers with the relative commands. thanks a lot in advance The following 7 questions are based on the CO2 dataset of R. 1) How many of the plants in CO2 are Mc2 for Plant? 2) How many are either Mc2 or Mn2?

I need to compute the mean and the standard deviation of a data set and would like to have the results in one table/data frame. I call tapply() two times and do then merge the resulting tables to have them all in one table. Is there any way to tell tapply() to use the functions mean and sd within one function call? Something like tapply(data$response, list(data$targets, data$conditions), c(mean,

Dear R-users, A while ago, Deepayan Sarkar suggested some code that uses the group argument in bwplot to create some 'side-by-side' boxplots (https://stat.ethz.ch/pipermail/r-help/2010-February/230065.html). The example he gave was relatively specific and I wanted to generalize his approach into a function. Unfortunately, I seem to have some issues passing the correct arguments to the

Hello all, I have a data frame with year, month, species, fishing gear and catch (Y, M, S, F, C) and I want the sum of C by Y for species "A" and fishing gear "trawl". I tried things like aggregate(C[S=="A" & F=="trawl"], list (Year = Y[S=="A" & F=="trawl"]), fun=sum), but it didn't worked. To overcome this problem I did

Hello, I am trying to use "bwplot" to display whisker boxes according to some conditioning factors ("age" has two values 1/2). I get the following messages: > library(trellis) > bwplot(dvk95~age|site*season,panel=function(x,y){panel.bwplot(x,y)}) Error in tapply(1:0, structure(list(INDICES = numeric(0)), .Names = "INDICES"), : arguments must have

I want to turn off selected axes in bwplot. I would like to only have the bottom axis drawn, with the others off. I have a series of bwplots that I want on one device, like this: p1<-bwplot(x1,box.ratio=.1) p2<-bwplot(x2,box.ratio=.1) ... print(p1,position=c(0,.8,1,1),more=T) print(p2,position=c(0,.6,1,.8),more=T) ... I know about the panel functions panel.bwplot() and panel.axis(), but

Hi, I have 2 questions about bwplot in R : 1) How to change the order of my different boxes in the graph ? 2) How to rename the names of the differents boxes ? because I know how to do that with boxplot (using names) but I do not find the equivalent parameter in bwplot. thanks, C?dric

Try factor(vec2) in your bwplot() call. -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch]On Behalf Of Ernesto Jardim Sent: Friday, July 09, 2004 9:41 AM To: Mailing List R Subject: [R] Problem with bwplot Hi, I'm ploting some box-and-whisker plots with bwplot but I'm not getting any box-and-whiskers ... just dots.

Dear r-helpers, tst <- data.frame(as.numeric(x <- 1:20), f <- rep(c('hi','lo'), times = 10)) with(tst, bwplot(f ~ x, panel = function(x, y){panel.bwplot(x, y, pch = '|', stats = boxplot.stats, fill = 8, varwidth = T)})) I can't figure out from the documentation how to tell stats that I would like to see notches or (even bands). Here is what I've

Can anyone point me to examples with R code where bwplot in lattice is used to order the boxes in ascending order? I have found the following discussion and it partly works. But, I have a conditioning variable, so my example is more like bwplot(var1 ~ var2|condition, dat) Th example in the discussion below works only when there is not a conditioning variable as far as I can tell. I can tweak the

I've looked again at Deepayan Sakar's 'Lattice' book and not seeing the information I know must be in there. A clue stick would be much appreciated. A pair of box-and-whisker plots for two conditions of the same data set display each box plot horizontally (see attached pH figure). Relations of the two are not as easily seen as they would be if the two panels had the plots

Hello, If you run the following code with lattice installed: bwplot(voice.part ~ height, data=singer, xlab="Height (inches)") There will be some text in the graph e.g. Soprano 1, Soprano 2, etc - 60, 65, etc and the title: Height (Inches). How can one make the font for this text larger and/or bold? Also, is there a way to thicken or bold the lines of the box and whisker plot? Thank

Inspired by colouring the dots of box-whisker plots I am trying to also fill the boxes (rectangles) with different colours. This seems not to work as I expected. Looking at the help page of panel.bwplot it says: 'fill - color to fill the boxplot'. Obviously it is only intended to fill all boxes with only one colour? Nevertheless the following example shows, that 'fill' from

Hello everyone I have dataset containing a monetary value (ABS) and two factors (Fct, Group). I am able to create useful using: bwplot(ABS~Group|Fct) and dotplot(ABS~Group|Fct) Question: What do I have to do to overlay the dotplot with the bwplot (same data set)? I've found a couple of posts that hinted at the possibility of doing that, and checked the panel.superpose() help, but the info

Hi, Is there some alternative to the 'groups' argument in lattice's bwplot function for boxplots? Say in the example below: bwplot(yield ~ site | year, data = barley) you want to have two side by side boxplots per site, corresponding to each year in the barley data frame. Ideally, the space between boxplots of the same site should be smaller than that between boxplots of different

Dear All, is any way I can change the colours of the box and umbrella of a bwplot without having to go to the length of: box.rectangle<-trellis.par.get("box.rectangle") box.rectangle$col<-"black" trellis.par.set("box.rectangle", box.rectangle) etc... but straight from the call: bwplot(y ~ x | z, mydata) ? Regards, Federico Calboli

Hi, I am working with R 1.81. When I call bwplot() it prints the output to the windows device as it should. For example, d<-data.frame(y=c(2,3,4,5,12,14,16,11),x=c(rep("group1",4),rep("group2",4))) bwplot(y~x,data=d) This code results in a parallel boxplot. That is a single plot with 2 boxplots next to each other; a boxplot for "group1" and a boxplot

Hi everyone, I have just got different samples from a dataframe (independent and exclusive, there aren't common elements among them). I want to create a variable that indicate the sampling selection of the elements in the original dataframe (for example, 0 = no selected, 1= sample 1, 2=sample 2, etc.). I have tried to do it with ifelse command, but the problem is that the second line
