Hello! I have a continous distribution and would like to get mode (the most frequent value in distribution). I easily found mean, median and other basic thing but not mode function. Can anyone help? I know there my might be problems with multiple modes, but still I think that there should be a mode function in R. Please send mail to R-help list and me, so I can get response faster. Thank

Hello! # I have 3 vectors of values: values1<-rnorm(10) values2<-rnorm(10) values3<-rnorm(10) # In real life, all 3 vectors have a length of 25 # I create all possible combinations of 4 based on 10 elements: mycombos<-expand.grid(1:10,1:10,1:10,1:10) dim(mycombos) # Removing rows that contain pairs of identical values in any 2 of these columns: mycombos<-mycombos[!(mycombos$Var1

Hi, I'm facing this problem quite a lot, so it seems worthwhile to check to see what the most efficient solution is. I've two vectors x (values ordered) and y. I've ranges x < x0, x0 <= x < x1, x1 <= x < x2, x2 <= x < x3, x > xn and want to construct a subvector yprime of y which consists of the first/last value of y whose x values are in the range. For

Ooops! Sorry, I send it only to Uwe Ligges the first time. Best, Philippe Grosjean This is perhaps another solution, more elegant in the way the block comment is written... but it requires to redefine `!` and slows it a little bit because it tests first its arguments before calling .Primitive(!): It takes advantage of `!` being not defined for character arguments: > !2 [1] FALSE >

I have a Lattice plot in which I want to adjust the number of tick marks used, and I want to have the drawn grid reflect that change. Here is what I'm doing: bwplot(var1 ~ var2, data=df, scales=list(tick.number=10), panel=function(...) { panel.grid(h=0,v=-1,...); panel.stripplot(col="gray40", pch="|", cex=2, ...); panel.bwplot(...); })

Hi. I'm using Samba 4.3.11 as a domain member on FreeBSD 10.x. Some of my users (around 1%) are experiencing problems from time to time, browsing this server's shares in Windows Explorer - it starts to ask for the password. It doesn't ask the password while accesssing it via it's IP address, and I see in its logs the following (when accessing it via its name): [2016/09/20

Hi. FreeBSD 8.2-RELEASE Samba 3.4.9 security = ads Samba as domain member. Controllers on Win2008 R2. When using IPv4 all is fine.

I.e. when password server = <NAME>, which resolves to AAAA, winbind says ===Cut=== # wbinfo -t checking the trust secret via RPC calls failed error code was

Hi, I have one question on expand.grid() function. When I write following syntax :expand.grid(c("u", "l"), c("u", "l"), c("u", "l")) I get following as desired : Var1 Var2 Var3 1 u u u 2 l u u 3 u l u 4 l l u 5 u u l 6 l u l 7 u l l 8 l l l However

Dear all, I am using expand.grid for calculating all the possible values between four pairs. I would like to ask you if it is possible to filter the result out, so to keep all unique pairs. In my algorithm the input c(1,2) produces the same results as the c(2,1) so for example in the following code below > expand.grid(c(1,2,3),c(1,2,3))   Var1 Var2 1    1    1 2    2    1 3    3    1 4   

Hello All: The function expand.grid() does nearly exactly what I want for permutation tests I wish to carry out, and it does so quickly when the number is kept small as in the example below: expand.grid(rep(list(c(-1, 1)), 3)) Var1 Var2 Var3 1 -1 -1 -1 2 1 -1 -1 3 -1 1 -1 4 1 1 -1 5 -1 -1 1 6 1 -1 1 7 -1 1 1 8 1 1 1 Understandably,

Hello! I have a list of variable length. One example is: X=vector("list",3) X[[1]]=1:2 X[[2]]=1:2 X[[3]]=1:2 How could I run expand.grid on the elements of X so that the results would be the same as expand.grid(1:2,1:2,1:2)? Thank you!

Hi, I was hoping someone could help me. I am a graduate student new to using R, and I'm trying to figure out how to recode a continuous variable to make it into an ordinal variable with 3 categories. I literally have no idea how to proceed--could anyone possibly advise me? Please copy me on any responses, as I have just subscribed to the R-help email list but don't know whether the

Hi, I am extremely new to R, and was wondering if someone would be able to help me with a question regarding the expand.grid function. When I input expand.grid.rep <- function(x, n=1) do.call(expand.grid, rep(list(x),n)) expand.grid.rep(c("a", "b", "c"), 3) my output is as follows, Var1 Var2 Var3 1     a    a    a 2     b    a    a 3     c    a    a 4     a  

Hi everyone (again), before you all start screaming that the reordering of factors has been discusse on several threads and is not particular to ggplot2, hear me out. I can easily reorder my x-axis factor in facet.grid() in ggplot2. What I cannot reorder are the factors represented on the strips. I can see that the graphs are changing, so I am afraid of what it is I am doing. Why is ggplot2

Hi everyone! #I need a loop or a function that creates a X2 variable that is X1 without the extreme values (or X1 winsorized) by industry and year. #My reproducible example: firm<-sort(rep(1:1000,10),decreasing=F) year<-rep(1998:2007,1000) industry<-rep(c(rep(1,10),rep(2,10),rep(3,10),rep(4,10),rep(5,10),rep(6,10),rep(7,10),rep(8,10),rep(9,10), rep(10,10)),1000) X1<-rnorm(10000)

Hi, # For publications, I am not allowed to repeat the axes. I have tried to remove the axes using: # yaxt="n", but it did not work. I have not understood how to do this in ggplot2.
