Hi all, I try to make a program for comparison between matrix cells. Here um simple example: 3 |a b a 2 |b b b 1 |a b a ------- 1 2 3 This is tabulated like this: x y sp 1 1 a 1 2 b 1 3 a 2 1 b 2 2 b 2 3 b 3 1 a 3 2 b 3 3 a Then, I need to make the follow calcule: ============================================== Change in sp levels from 1x1 area to 2x2 area:

Hi, I try to make a vector in a for for loop, but it dont work. Look: > a <- 0;for(i in c(1:2)) { for(j in c(1:2)) { a <- i+j; print(a)}} [1] 2 [1] 3 [1] 3 [1] 4 I try to make this a vector, like this: [1] 2 3 3 4 > a <- 0;for(i in c(1:2)) { for(j in c(1:2)) { a[j] <- i+j}}; print(a) [1] 3 4 > a <- 0;for(i in c(1:2)) { for(j in c(1:2)) { a[i] <- i+j}}; print(a) [1]

Hi, I try to make a key alias to XEmacs+ESS function Complete File Name. But I dont know the name of this funcion. Anybody know how this funcion is call?

Hi, I have this non-linear function: y=115.251 - 118.69 * exp(-0.123517*x) I try to discovery the x value for the assyntoptic value of y and the x value where the behavior of curve change, the inflection point. How to make this? Is poss?ble to make this on R? Thanks Ronaldo -- O Flamengo e o Bangu terminaram o jogo em 0 x 0. Quem fez o gol? A Volkswagen -- | // | \\

Ronaldo Your mathematical question is of interest to me too. But I am particularly interested in a translation into American English of the pun attached to you email. Could you try to explain O Flamengo e o Bangu terminaram o jogo em 0 x 0. Quem fez o gol? A Volkswagen My rough translation into English is: Two soccer teams ended play 0 to 0. Who got the goal? A Volkswagen. I need all the

Hi all, I'm here again with my newbies questions :( I have a simple example: count of slugs in two fields. I need to make a barplot with mean and SE of mean. So I have: The mean: > tapply(slugs,field,mean) Nursery Rookery 1.275 2.275 The SE: > tapply(slugs,field,sd)/sqrt(tapply(slugs,field,length)) Nursery Rookery 0.3651264 0.3508004 If the data has been normally

Hi, I try to make a function that have two others functions inside. It is simple, but the problem is that functions inside use the same variable, but with different values. I try something like this: Teste <- function(Pdig(nlinhas),Ldig(nlinhas)) { Pdig <- function(nlinhas) { Tdig <- (15.50 + 7.45*nlinhas); (3*(Tdig*(30/3600))+1*(30*(30/3600))); } Ldig <- function(nlinhas) { Tdig

Hi, I try to make a dataframe in a loop function, but I dont have succeed. The function is something like this: for(i in c(10,12)) { expr for(j in c(1:2) { total <- c(1,2,3,4,5,6,7) nspf <- length(levels(as.factor(total))) fin <- data.frame(L=i,N=nspf) print(fin) } } This print something like this: L N 1 10 7 L N 1 10 7 L N 1 12

Hi, I make a nested lme analysis, it is ok. The estructure is: lme(y~x,random=~1|x/animal) It is no the exactly formula, but the teoretical formula. The real formula have a new variable with x/animal group. Now I try to construct a nested lme table like the traditional anova table to presentation of the data. --------------------------------------------- | Source | SS | d.f. | MS | F

Hi, I use R with XEmacs and ESS, when I'm editing a R file in XEmacs, the delete key work like the Backspace key. This behaviour is only in XEmacs + ESS + R file, it dont have this behaviour on a R section (M+R). Anybody know how to make a delete key to work like the delete key??

Hi, I have the follow situation in a ancova analysis: y (count data) x1 (continuous data) x2 (qualitative data) x2 have 10 levels (a,b,c,d,e,f,g,h,i,j) I make the model m1 <- glm(y~x1*x2, family=poisson) then I want to remove the levels h, i and j (make these levels with intercept = 0 and slope = 0) A make a new datafile without these levels. This new table is smallest than the

Hi, Normally I make survival analysis using survreg in survival package. It is simple to compare curves for different levels. But in this case all curves have the same estimated scale parameter. In some cases, curves are graphically different in your behaviour. One curve is like type I curve (1/scale > 1). Other curve is like type III curve (1/scale < 1). All graphics made normal and

Hi, thanks for help on index in a for for looping. its work. Now I have another doubt. I have a data.frame like this: nsps area 1 1 4 2 0 9 3 1 4 4 1 4 5 1 4 6 1 9 7 0 4 8 1 9 9 0 4 10 1 9 ... I try to make another data.frame like this: nsps area 1 4 4 2 3 9 using tapply, it work: >

Hi, If I have the follow example: y = count data x1 = continuous data x2 = qualitative data (2 factors levels) I make a model glm(y~x1,family=poisson) The model has only one curve, to calculate r-square, I do "x1 Deviance"/"total Deviance" But in a model with x2 glm(y~x1+x2,family=poisson) I have two curves, but I dont have, using summary() or anova(), the deviance

Hi all, I have problems in a dataframe variables types. Look: from a loop function: for(...){ ... dados.fin <- rbind(dados.fin, c(L=j, A=j^2, Nsp=nsps, N=length(amosfin$SP), AmT="am",NAm=nam, AMST=amst)) dados.fin <- rbind(dados.fin, c(L=j, A=j^2,

Hi, I have a new (for me) situation. I have a function for one linear model: y = 9.7909-0.035*x I have the variance of system var = 13.01403 Is possible to create a random vector points of Y (simulating the real data) over this curve using the function and the variance? I need this to a discipline. I have this: | \ | \ -> y = 9.7909-0.035*x and var = 13.014 | \ | \ | \ | \

Hi all, I have a little problem. I make an weibull survival analysis using the survival package. It,s OK, them I have the functions. I plot this funcions with curve(). I want to make a plot with the real survival points (proportion of alive x time) and them add the curves to points. I have the time to dead, the censor data and my trataments. To analysis the model is: model1 <-
