similar to: Sort a data frame

Dear ALL, I fear my question has already been answered many times before, but I haven't fund that in archives... I am working on spatial datasets and, in most arrays I'm handling, there are two columns dedicated to (x,y)-coords. For different reasons - notably to draw image() plots, I need to have these two columns sorted in increasing order. But sort() and order() seem to apply to

R-help, I have a list of several data frames. I want to compute the "rowSums" of the columns of these data frames but first one. Something like this lapply(my.list,rowSums) Thank you Luis Ridao Cruz Fiskiranns??knarstovan N??at??n 1 P.O.

R-help Assignments within functions are local and temporary,right?(function 1) If arguments to another function (function 2) are objects created in function 1 and need to call function 2,,,,,,,then it won't work,Am i right? I have nested the functions but still do not work. How can this (it may be simple but I don' know how to get around this) be done?? Thank you Luis Ridao Cruz

Still wrong: > x <- data.frame(a = sample(letters[1:3], 10, replace=T), b=1:10) > x a b 1 a 1 2 a 2 3 b 3 4 b 4 5 a 5 6 a 6 7 b 7 8 b 8 9 b 9 10 c 10 > subset(x, a == c("b", "c")) a b 3 b 3 7 b 7 9 b 9 10 c 10 > subset(x, a %in% c("b", "c")) a b 3 b 3 4 b 4 7 b 7 8 b 8 9 b 9 10 c 10 What matters

sorry for my previus (WRONG) answer, as someone already pointed out a solution could be subset(data, PUNTAR==c("IX49","IX48")) > -----Messaggio originale----- > Da: Guazzetti Stefano > Inviato: venerd?? 23 luglio 2004 15.55 > A: 'Luis Rideau Cruz'; r-help at stat.math.ethz.ch > Oggetto: R: [R] retrieve rows from frame assuming criterion > >

Hi all, I want to fill in this matrix vectors (by column) without overwriting the first elements in column 1995. Is there any other way than concatenate the first element with the vector and then assign this new vector to the column in matrix? matrix[,"3"]<-c(1591,"vector") matrix[,"4"]<-c(405,"vector") ... ...

R-help, I'm trying to work out the density function by doing: > df(5.22245, 3, 22) [1] 0.005896862 > df(15.20675, 6, 4) [1] 0.001223825 In excell the result is : 0.0071060464 <*> FDIST(5.22245,3,22) 0.0100001406 <--> FDIST(15.20675,6,4) >From my point of view the differences in the second case are substantial. Can anyone give me a hint on this? Thanks in
