Plotting US States: Issue with filled colors cycling
I'm having issues when trying to do a filled State plot using the maps() package. It seems that the color values aren't being plotted correctly, and I'm not sure why... I've started debugging it, but I'm stuck. I've attached the code that I've got so far. The for loop plots states 1:i. What I'm noticing is that the colors are correct until after Michigan gets

Plot
Hello, I am trying to make a plot of the rates of an enzyme against three different protein concentrations (there are 45 rates in total and split up into 3 groups of 15, each receiving one of the 3 protein concentrations). When I enter the following code I instead get 3 separate boxplots for each of the three different protein concentrations ... plot(rate ~ ferm, data=LDH, col=LDH$rate,

Code find exact distribution for runs test?
I've been attempting to understand the one-sample run test for randomness. I've found run.test{tseries} and run.test{lawstat}. Both use a large sample approximation for distribution of the total number of runs in a sample of n1 observations of one type and n2 observations of another type. I've been unable to find R code to generate the exact distribution and would like to see how

double-indexed list
Dear all, d, d=1,...,10 is a day, h, h=1,...,24 is an hour and tt_dh(1),tt_dh(2),... is the arrival time of the 1st, 2nd etc client on day d during hour h. How can I make a double-indexed list ldh (indices are d and h) such that ldh[[d,h]] gives me arrival times? Many thanks, Remi [[alternative HTML version deleted]]

SVM plot duda
Hola, El mensaje es claro: el modelo svmfit no existe, tú has llamado al ajuste ?modelo?. De todas formas, aparte de eso tendrías que especificar qué dimensiones (variables predictivas) quieres representar. Si miras en la ayuda de ?plot.svm lo tienes explicado. Esto sí funcionaría: plot(modelo,df11, LDH ~ INL ) Gracias por proporcionar el código y los datos para poder reproducir el error. Un

survreg.distributions() error
Hi there. I am receiving an unexpected error message when creating a new distribution for the survreg() function in the survival package. I understand the survival.distributions() function and have been following the Cauchy example provided in the help file. My goal is to use survreg to fit a gamma distribution to interval censored data. Here is a simple example of what I'm trying to do.

summary() of lm() problem (PR#135)
Debuggers, I wrote to r-help about this and was appropriately told off by Peter Dalgaard. I append that mail in case you have not seen it. Following Peter's advice I have attempted to simplify the problem. First note that the following does *not* fail (by which I mean crash, as in generate a memory access violation): > tmp<-matrix(c(1,0,0,1,1,1),2,3) >
