HI Eliza,
You could do this:
set.seed(15)
mat1<-matrix(sample(1:800,124*12,replace=TRUE),nrow=12) # smaller dataset
#Your codes
?list1<-list()
?for(i in 1:ncol(mat1)){
? list1[[i]]<-t(apply(mat1,1,function(x) x[i]-x))
? list1}
?x<-list1??
x<-matrix(unlist(x),nrow=12)
x<-abs(x)
?y<-colSums(x, na.rm=FALSE)
z<-matrix(y,ncol=10)
?z<-as.dist(z)
?z

HI Elisa,
You could use ?cut()

label1<-unlist(lapply(mapply(c,lapply(seq(0,45,5),function(x) x),lapply(seq(5,50,5),function(x) x),SIMPLIFY=FALSE),function(i) paste(i[1],"<x<=",i[2],sep="")))

In the example you showed, there were no column names.?

loop for column substraction of a matrix
Dear useRs,
I have a matrix with 38 columns and 365 rows. what i want to do is the following.....
1. subtracting from each column, first itself and then all the remaining columns. More precisely, from column number 1, i will first subtract itself(column 1) and then the remaining 37 columns. Afterwards i will take column number 2 and do the same. In this way i want to proceed till 38th column.

efficient overlapping average curve on original curves
Dear useRs,
my question could be very basic for which i apologize in advance.
Each column of a matrix with dimensions 365 rows and 37 columns was drawn against another matrix of dimensions 365 rows and 1 column. with that i was able to draw 37 curves on the same axis.
now i want to draw an average curve of these 37 curves on the same axis in such a way that all the curves (average and 37

call a variable from outside of for loop
Dear useRs,
While using print command in "for" loop, i designated a variable being printed by "e". Although the output was shown inside the loop but when i tried to call the variable outside the loop it only gave the first row, where as it should have 35 rows as it showed inside loop.The command which i used in the loop is
e<-print(sum(abs(b-m[,i])))
Kindly help me on it..
