Thanks to David's help I subset my large data set and produced a smaller one for a single stream and 7 factors of interest. The structure of this data frame is: str(burns.tds.anal) 'data.frame': 718 obs. of 4 variables: $ site : Factor w/ 143 levels "BC-0.5","BC-1",..: 1 1 4 6 4 4 4 5 5 5 $ sampdate: Date, format: "1996-06-02"

Hi All: I was recently working with a dataset on arsenic poisoning. Among the variables in the dataset, I used the following three variables to produce crosstabulations (variable names: FOLSTAT, GENDER, ASBIN; all three were categorical variables, FOLSTAT denoted follow up status for the subjects and had seven levels, GENDER denoted sex (two levels: male,female), and ASBIN denoted binarized

I have measured values for 47 chemicals in a stream. After processing the original data frame through reshape2, the recast data frame has this structure: 'data.frame': 256 obs. of 47 variables: $ site : Factor w/ 143 levels "BC-0.5","BC-1",..: 1 1 1 2 2 2 2 2 2 2 ... $ sampdate : Date, format: "1996-04-19" "1996-05-21" ... $ Acid :

I am trying to make a x-axis and y-axis titles with both a special character and a subscript. I am not being able to do this. I think its just a placing of my parenthesis, but I've tried (seemingly) everything. Even more, when I try the blog users code it works. Is it because I?m using longitudinal data? Even more. Is it possible to colour each one of the 15 lines with a different

Dear colleagues, I often use chemical formulas to label my x-axis, e.g. in barplots. I used to do this like the following example and it worked just fine: a <- seq(2,24,2) b <- seq(3,36,3) c <- rbind(a,b) barplot(c, width=c(0.9, 1.1),space=c(0.2, 0.75), col=c("indianred4", "yellow2"), beside = TRUE, xlab="Ions", yaxt="n", xaxt="n", ylab

Hi Rosa something like plot(1,1, sub=expression(lambda^"2")) So with your example, do you want something like plot(c(1:5), CRP7raw[1,], type = "n", xlim=c(1,5), ylim=c(-10,5) , xlab="Day in ICU", ylab="CRP (mg/dL)", sub = mtext(expression(lambda^2))) CRP7graph <- apply(CRP7, 1, lines, col="gray") Cheers Petr >

Hi, If I have data as follows: DATA_names<-c( "A mg kg" "B mg kg" "C mg kg" "D mg kg" "E mg kg" "F mg kg" "G mg kg" "H mg kg" How do I convert to: -1 A (mg kg ) -1 B (mg kg ) -1 C (mg kg ) -1 D (mg kg ) -1 E (mg kg ) -1 F (mg

All, On p.52 of Deepayan Sarkar's Lattice book there is a nice plot of showing residuals with median lines superimposed or various groups: library("lattice") stripplot(sqrt(abs(residuals(lm(yield~variety+year+site)))) ~ site, data = barley, groups = year, jitter.data = TRUE, type = c("p", "a"), fun = median) Suppose we wanted to make a similar plot for a

Dear List, ? I am creating a boxplot with two subsets, very similar to the example by Roger Bivand at ?boxplot (reproduced below).? I am trying to change the labels on the x-axis to have one number to cover both subsets.? I can do this in other plots by using axis=FALSE followed by a separate axis() command.? I have also tried variations in the names= argument but can't get it to work.?

Dear Rxperts, Running the following code: ======================================================= twlo=10; twhi=20; wt=154; vd=0.5; cl=0.046; tau=6; t=3; F=1; wtkg <- wt/2.2 # convert lbs to kg vd.pt <- wtkg * vd # compute weight-based vd (L) cl.pt <- wtkg * cl # compute CL (L/hr) k <- cl.pt/vd.pt # compute k (hr^-1) cave <-

Hi, everyone, Before everything, thanks. Lots of thanks ;)!!!! I don?t think you understood everything I need to do. I want to write t_i instead of "Day in ICU? [i subscript for t] and y_ij instead of "CRP (mg/dL)? [ij superscript for y]. The label of the axis? :( Can you help me on that task? Thanks!!!!!

I'm having an sorting problem in dotchart. I want to change the order of the BA in groups to AB, but I haven't found any solution yet. What should I do? And what if I want to change the groups order as well? At the bottom from Conrol up to 10 mg/L on the top. Thank you! x = c(39, 23, 23, 35, 30, 26, 30, 30, 29, 29, 26, 29, 34, 33) y = c("Control", "DMSO", "0,1

The example below creates parallel time-series plots of three different y variables conditioned by a dichotomous factor. In the graphical layout, ? Each y variable inhabits its own row and is plotted on its own distinct scale. ? Each level of the factor has its own column, but within each row the scale is held constant across columns. ? The panels fit tightly (as they do

Hi, I need to add some different curves to a each panel in a xyplot. I have a old function to make this using panel.number, like this: panel=function(x,y,panel.number,...){ panel.xyplot(x,y,...) if(panel.number==1){ panel.curve(-655.8689+769.1589*log(5)+64.7981*log(x)-206.4475*log(5)^2) } if(panel.number==2){

Hi, I try to change the panel name in a xyplot without success. Look this example from xyplot manual: xyplot(Murder ~ Population | state.region,data=states) The panel title are: Northeast, South, North Central, West, that are factor from state.region. I need do change some names and, for example, put some of these in italic. I dont find how change this. I looking for this in Deepayan

Hello, I have a problem with creating an identity matrix for glmnet by using the contrasts function. I have a factor with 4 levels. When I create dummy variables I think there should be n-1 variables (in this case 3) - so that the contrasts would be against the baseline level. This is also what is written in the help file for 'contrasts'. The problem is that the function
