Hello R-users, I am trying to obtain Type III SS for an ANOVA with subsampling. My design is slightly unbalanced with either 3 or 4 subsamples per replicate. The basic aov model would be: fit <- aov(y~x+Error(subsample)) But this gives Type I SS and not Type III. But, using the drop() option: drop1(fit, test="F") I get an error message: "Error in

Dear all, I was trying to see how the function 'confint' is defined. Doing > confint function (object, parm, level = 0.95, ...) UseMethod("confint") <environment: namespace:stats> does not really enlighten me. How can I get to see the implementation (I guess it should be possible according to the general philosophy of the R project)? Thanks in advance S??ren

Dear r-devel list members, On a couple of occasions I've encountered the issue illustrated by the following examples: --------- snip ----------- > mod.1 <- lm(Employed ~ GNP.deflator + GNP + Unemployed + + Armed.Forces + Population + Year, data=longley) > mod.2 <- update(mod.1, . ~ . - Year + Year) > all.equal(mod.1, mod.2) [1] TRUE > > f <-

What does missInfo compute and how is it computed? There is only 1 observation missing the ethnic3 variable. There is no other missing data.

Hello, I am using the recode() function in Rcmdr and the result is not what I expect so I am almost sure I did something wrong but what... > test <- data.frame(x=1:10) > library(car) > recode(test$x,'1:5=0 ; else=1', as.factor.result=TRUE) [1] 0 0 0 0 0 1 1 1 1 1 Levels: 0 1 BUT > library(Rcmdr) # recode from the car package is now masked Now I recode test$x

Good morning, I'd like to look at the code for the R function head. When I type just the word head, I get back function(x, ...) UseMethod("head") <environment: namespace:utils> I expected to see several lines of R code. Any suggestions? Thanks, Walt Paczkowski

Dear R Users, I have a question, how does one print an r function like t.test in R (to get the whole function and not just a summary of the environment)? For example if I type the following: > t.test function (x, ...) UseMethod("t.test") <environment: namespace:stats> > print(t.test) function (x, ...) UseMethod("t.test") <environment: namespace:stats> I

Hi R users, I have a question. How can I see the code behind the function. For example, > boxplot function (x, ...) UseMethod("boxplot") <environment: namespace:graphics> I really would like to see how people code this. Could someone please show me how to see the code behind the function? Many Thanks Tu -- View this message in context:

Hello Pardon for the elementary question, I did try searching the archives with various terms, but to no avail. I am using R1.9.1 on a windows machine One of the great advantages of R (to me, anyway) is being able to see the code for a function , e.g. by typing sd one sees the code for getting a standard deviation. However, for many functions this only provides info. including UseMethod, eg.

R-help, Sorry for this question (I guess it has been addressed before but I could not find it in the archives) but how can I see a function code when the following comes up: > svymean function (x, design, na.rm = FALSE, ...) { .svycheck(design) UseMethod("svymean", design) } <environment: namespace:survey> Thanks in advance

Dear R users: I am looking for the source code for the R function extractAIC. Type the function name doesn't help: > extractAIC function (fit, scale, k = 2, ...)

Greetings, I am trying to figure out how to find the source code for R functions. I am specifically interested in finding the code for the "prcomp" function. I know that typing the function name without parenthesis will lead to the code (or to a .Internal or .FORTRAN or .C call). However, I don't really understand what is going on. For example, typing "mean" gives a

Buenos días: Otra opción es escribir directamente el nombre de la función en la consola de R: > randomForest function (x, ...) UseMethod("randomForest") En este caso, la función randomForest() llama a UseMethod() para seleccionar el método adecuado. Podemos ver los métodos para randomForest con la función methods(): > methods(randomForest) [1] randomForest.default*
