I have a data set with four columns and need to make boxplots from them. Data is as follows: tank Tanks Total cons_hat 1 a a4 5.651017 5.59 2 a a5 5.017499 5.29 3 a a6 4.894238 4.69 4 c c4 3.986347 3.40 5 c c5 4.099442 3.58 6 c c6 4.150522 3.64 7 h h4 5.187792 6.32 8 h h5 6.713422 6.44 9 h h6 5.168555

Hi all and thanks in advance. I am regressing Time and Weight, and then predicting Weight at different Time. The format of the Time data is day/month/year. How can I get R to use time series data such as this? Keith -- M. Keith Cox, Ph.D. Alaska NOAA Fisheries, National Marine Fisheries Service Auke Bay Laboratories 17109 Pt. Lena Loop Rd.

I have re-labeled tick marks on the x axis. The problem is that by using axes=FALSE, the axes disappears and when they are called back using axis(side=1)..etc. the axis on sides 1 and 2 do not meet at the bottom left corner of the graph. I would also like to have the 3rd and 4th axes in there as well, all meeting in their respective corners. par(mfrow=c(1,2)) gut<-c("Full",

Hello, hopefully simple question, but I cannot find the answer. I need to change the color from the standard default. Still want the scaled colors, but need different colors for different graphs. Code is: wireframe(z ~ y*x, mat.df, drape = TRUE, zlab = list("Water mass error (%)",rot=92), zlim=c(-50,180), xlab = list("Resistance error

Hi, I would like to add a color under a lm line and not the plotted line. Is this possible? In the example, I do not want the area under the curve red, but rather under the llm line. x=seq(0,5,len=100) y=-(x-5)^2 llm<-lm(y~x) plot(x,y) polygon(c(x,x[length(x)]), c(y, y[1]), col='red') abline(llm) keith -- M.

Hi , I am new to R . I am facing difficulty how to make pairwise comparisions. For example. I have a file which looks like below a b c d x 3 6 7 6 y 7 8 6 5 z 5 4 7 8 Here I need to look for the each pairwise comparisions (ab,ac,ad,bc,bd,cd for each row) For instance ,looking at first row, for x i need to look for ab values and take the min(3,6) >5 ,if its satistfies the count should be

I would like to calculate a first and second derivative and am having problems finding a simple solution. My syntax may be off as I am not a mathematician, so pardon ahead of time. data: t<-seq(0,4, by=.1) The function is: H(t) = t^3-6*t^2+5*t + 30 from here I plot the curve: plot(x,y ,xlab="x-values", ylab="f(x)", type="l") But would like to similarly plot the

R users, This should be simple, but I cannot figure it out. I import test.csv, then create a subset for "brook_dis". When I plot (week, R) I get a nice boxplot, but along the x axis, there are weeks a, b, c along with h and nh. Thank you ahead of time. keith rm(list=ls()) cond.exp1<-read.csv("condition/test.csv",header=TRUE) sub<-subset(cond.exp1,

I have long axis labels (8units) on the x axis and 2 unit number labels on the y axis. I need to move the x axis title without moving the y axis title. I have used mgp=c(title, label and line), but mgp moves both the x and y titles. The following puts the y axis title way way out to the left. Anyone know how to move just the x axis. X11() conif<-c("Control", "Switched

This data are kilojoules of energy that are consumed in starving fish over a time period (Days). The KJ reach a lower asymptote and level off and I would like to use a non-linear plot to show this leveling off. The data are noisy and the sample sizes not the largest. I have tried selfstarting weibull curves and tried the following, both end with errors. Days<-c(12, 12, 12, 12, 22, 22, 22,

I need a two sample t.test between M and F. The data are arranged in one column, x. Cant seem to figure how to run a two sample t.test. Not really sure what this output is giving me, but there should be no difference between M and F in the example, but summary p-value indicates this. How can I run a two sample t.test with data in one column. x=rep(c(1,2,3,4),2)

OK, this is very elementary, but I need help. I have looked in Verzani, past postings etc. Problem: I need to subtract the "length" date between "h4" and "a3" #which would be 4-1 I would rather not convert the two columns into four columns (with headings being "a3","a4","c4","h4"). DF <- data.frame(length=c(1,2,3,4),

I posted this earlier, but am not certain that it was in fact posted, so I will try again. Hi, I have an equation Xcp and would like to look at errors affecting it. I am applying errors of -.58 to .1 to R and -.45 to .47 to Xc. I would like to look at all combinations. I set up a matrix function as follows and it does not work. On the last line, when it run, it does not seem like the two X’s

I need grayscale formatting for a wireframe. The only col.regions that I can find are color palettes are all colored: rainbow(n, s = 1, v = 1, start = 0, end = max(1,n - 1)/n, gamma = 1, alpha = 1) heat.colors(n, alpha = 1) terrain.colors(n, alpha = 1) topo.colors(n, alpha = 1) cm.colors(n, alpha = 1) The code follows: X11() library(lattice) par(family="serif", cex=1.2)

Z is a matrix and when I run the following line, it creates a prediction estimate using each column, how can I get it an estimate for each individual number. I have tried changing Z to a data.frame, but this does not do it either. model.lm<-lm(w~x) pred.est <- predict.lm(model.lm, data.frame(x=Z)) Thanks in advance, keith -- Keith Cox, Ph.D. Sitka Sound Science Center Fisheries

Matt, I know you are probably busy with work, but I cannot help buy asking you these R questions.
