Dear Everybody, Enclosed are the tiny beginning of a program and its output. As a pity, if I load the image <load("kanal.RData")> the elements of <de.dd> are non numerical; <de.dd[2]+de.dd[3]> returns <Fehler in de.dd[2] + de.dd[3] : nicht-numerisches Argument f??r bin??ren Operator>. How can I keep the numbers numerical? Thank you in advance. hopefully, Mag.

Dear everybody! I am analysing data from an enquette. The answers are either A or B. How can I draw a histogram without transforming the data from characters to numbers?

Dear everybody! I am making a graph in R and employ pstoedit to expot the .pdf-output to .svg.

What does this warning mean precisely? Is there any reason to care about it? Can I Avoid it by another way of programming? Thank you in advance.

unique(x) will give you the distinct values in x. table(x) will give you the distrinct values and their frequencies as an array with dimnames. data.frame(table(x)) will give you a 2-column data.frame with the distinct values and their frequencies. > values <- c("Small", "Large", "Large", "Large") > unique(values) [1] "Small"

Dear everybody! take a<-c(5,3,NA,6). if(a[1]!=NA){b<-7} if(a[3]!=5){b<-7} if(a[3]!=NA){b<-7} if(a[3]==NA){b<-7} will alltogeather return Fehler in if (a[1] != NA) { : Fehlender Wert, wo TRUE/FALSE n?tig ist (or simularly). Somehow this is logical. But how else should I get out, whether a certain vector-component has an existing value? Thank you in advance! Yours, Mag. Ferri

Dear Everybody! I want to export data to LaTeX. As I want to employ the data as freely as possible I want to avoid the xtable-command and instead generate some List like \MyOwnPrettyCommand{Adam}{Auer}{17} \MyOwnPrettyCommand{Bertram}{Bauer}{14} \MyOwnPrettyCommand{Christoph}{Huber}{75} \MyOwnPrettyCommand{Damian}{Dorfer}{69} \MyOwnPrettyCommand{Emanuel}{Eder}{43} with \MyOwnPrittyCommand

...l NA into 0 (zero) ? so I would have the following: temp type1 type2 a b c 1 male low 1 5 0 2 female med 2 0 0 3 male high 4 5 1 4 female low 0 1 1 5 female med 3 2 0 I've been trying with which() but without success. Any pointer is appreciated. Thank you, Ferry [[alternative HTML version deleted]]

...is, I have a lot more of than just two numerics and conditioning fields. In SQL, I would do: select v1, v2, sum(n1), sum(n2) from myData group by v1, v2; Am I using a wrong function / library (or even wrong approach)? If so, can you suggest which one? Any pointer is really appreciated. Thanks, Ferry [[alternative HTML version deleted]]

Dear everybody! If I have an array of numbers e.g. the points my students got at an examination, and a key to group the numbers, e.g. the key which interval corresponds with which mark (two arrays of the same length or one 2x(number of marks)), how can I get the array of absolute frequencies of marks? I hope I have expressed my problem clearly. Thank you in advance. Mag. Ferri Leberl

Dear everybody! Please find attached a tiny R-program. It returns: [,1] [,2] [1,] 53.55 NA [2,] 53.55 NA [3,] 53.55 NA How can I manage the first column to show the second component not only of the first list in k??ste but of the second component of every list in k??ste respectively, such as to get the following array returned: [,1] [,2] [1,] 53.55 NA [2,] 53.87 NA [3,] 53.87

Dear everybody! I have load a list A of numbers and want a histogram to be drawn. on hist(Y) the Machine returns: Error in hist.default(A) : `x' must be numeric I found out, that the list is of type data.frame. Y<-as.numeric(Y) returns Error in as.double.default(A) : (list) object cannot be coerced to double What schould I do? Than you in advance!
