Dear list, I'm trying to make a loop of a (5x10) matrix and below are my codes. Could anybody help me figure out why my loop is not working. Thanks in advance!! m<-1:5 n<-1:10 for(i in 1:length(m)) { for(j in 1:length(n)) { y[i,j]=sum(i,j) y<-as.matrix(y[i,j]) } } cheers, Anisah --------------------------------- [[alternative HTML version

Dear lists, I want to write a function of a vector and reverse the order of its elements. Here is my code: revector<-function(n){ y=vector(length=n) for(i in n:1){ y[i]=i } return(y) } i want my output to be like this: y [1] 10 9 8 7 6 5 4 3 2 1 Any suggestion?? Thanks!!

Dear R User, say I have this sample of data ( attach with). What i'm going to do is to test whether this data is uniformly distributed or not by finding the p-value. I've tried using the punif command but it gave me the value of 1 of all the data. Any suggestion on R command to find the p-value??Thanks in advance!! Cheers, Anisah -------------- next part

dear lists, My question is quite simple but i'm a new user in R and it's seem tough to me. How am i going to recall back my values??ok..it could be easy if i ilustrate my problem with the simple example. say that, x [1] 1 2 y [1] 2 3 and my logical output from my function are (Below is my function): overlapped(x,y) [1] TRUE [1] TRUE suppose i

hi!! Below I have 4 columns vector of c and d which are unequal in length.These c and d have 2 columns each where these 2 columns represent an interval values. How am I going to get an overlapping over these interval values?? Please help me sort this problem!! Thanks in advance.. c d 17130612 17587118 17712302 18100404 17712302

hi, I'm in my learning process of doing a programming with "for" loop. How to make a loop of a vector of length 10 where elements are 1,2,3,4,5,6,7,8,9,10. Any suggestion needed!! Many thanks. Cheers, Anisah --------------------------------- [[alternative HTML version deleted]]

Dear lists, Anysuggestion on how to write a loop function which has nx2 matrix as an input, where each of the row represents an interval. the function should return a mx2 matrix containing the no matched interval of x?? i've tried my own function but it's only applies for 2x2 matrix. Here is my code: overlap<-function(x,y){ m=length(x) n=length(y) for(i in 1:m){

hi, I want to plot a dotplot graph but unfortunately R does not have it any more. It suggest to use either the stripchart or the dotchart and i prefer to play around with the stripchart graph. Sadly, the result is not like i want where I'm actually wants the plots/points were scattered around the x-axis. Plus, from the results shows that and the x-axis gave a very large scale, i.e

Hi, I have a matrix data with 21 rows and 6 columns. Below and attach with is my matrix data. My problem is to split the column into 3 subcolumns (except for column 3 and 4) . I want my new matrix data to have 14 columns and 21 rows. Kindly help is highly appreciated. [,1] [,2] [,3] [,4] [,5] [,6]

I have two sets of interval data.Below are my two dataset. In these dataset, there is a missing values in each of the data. I want to find the non-overlapping interval values. Here is my code: mysetdiff=function(x,y){ m=length(x) n=length(y) bx = logical(m) by = logical(n) for(i in 1:m){ for(j in 1:n){ if(x[i]<=y[j]){ bx[i] = T by[j] = T }

Dear R-users, Attach with is my data..what i want to do is finding a suitable distribution for my data..I want to run a few test like the poisson and the exponential distribution. Please help me on how to find the p-value for poisson as well as the exponential distribution without knowing the parameter. Is it possible?? Thanks in advance. love, Anisah -------------- next

Dear R, Can anybody help me on how to combine all the elements in a list into a single vector?? I've tried using unlist command but it gave me wrong output. Below is the example of the vector output that i want and attach with is my list of data. Any suggestion?? Many Thanks breakp.start 6978022 10249966 10955201 11045352 11814604 13847633

Dear lists, any suggestion on how to write a function to return a TRUE if interval [a,b] overlaps the interval [c,d]. I've tried it but an error occur saying that 'could not find function v ; in addition warning message occur'. Below is my codes.Please help me sort this problem as i'm in process of learning of writing a function. Many thanks overlap<-function(m,n){

Dear lists, i want to find the non-overlapping interval values with this code: mysetdiff=function(x,y){ m=length(x) n=length(y) bx = logical(m) by = logical(n) for(i in 1:m){ for(j in 1:n){ if(x[i]<=y[j+1]){ bx[i] = T by[j] = T NA = NA } } } sx = x[!bx] sy = y[!by] s=c(sx,sy) return(s) } Below is my

hello!! say that i have the values of x1 and x2. my x1 has longer length than x2. how am i going to remove the similar values of x1 and x2. Any suggestion?? Thanks in advance!!

Hi, I have sucessfully plotted the graph by using the following command: ec<-rep(0,length(e)) fc<-rep(0,length(f)) plot(e,ec,type="p",col=1,pch=19) points(f,fc,col=2,pch=20) legend(1.0e+08,1.0,c("dog", "human"),text.col="green4",pch=c(19,20),col=c(1,2)) Below are the values for e and f...the questions is how am i going to adjust

Dear all, I have a data which is in text file and i would like to import the data to R.

Hi all, (if me email goes out as html, than my email client don't do as told, and I apologies already.) We need to downscale climate data and therefore first need to expand the climate from 0.5deg to the higher resolution 10min, before we can add high resolution deviations. We basically need to have the original data at each gridcell replicated into 3x3 gridcells. A simple for loop can do
