Dear sir, i have a matrix like x<-c(1:20) A<-matrix(x,4,5) > A [,1] [,2] [,3] [,4] [,5] [1,] 1 5 9 13 17 [2,] 2 6 10 14 18 [3,] 3 7 11 15 19 [4,] 4 8 12 16 20 I want to extract the column value for the matrix value 11... or the row value for 14.. how it is possible? thanks for your help.... with regards, boopathy.

Dear all, I like to extract row names & column names from the named matrix...... like...... a<-matrix(1:6,2) ro<-c("aa","bb") co<-c("dd","ee","ff") dimnames(a)<-list(ro,co) a > dd ee ff aa 1 3 5 bb 2 4 6 from the above matrix "a" I like to extract rownames separately like

Halo friends, I have a problem to solve in R graphics.. I have a matrix like A= 2 3 4 5 6 7 8 9 4 and I like to generate the same matrix in terms of shaded circles in which the density of shading depends on the value... for eg in the above matrix A the value 2 is a circle shaded very lightly 9 is of full dark

Dear all, While running a function I伌m getting only the final output of the function. Bit if I like to store or recover some values that are intermediate in the function calculations which command I have to use for storing those values..... hope u understand..... for eg........ a<-function(a,b,c,d) { k=a+b l=c+d m=k+l } in this example the function

Could anybody help me in mixing the matrix values randomly (first rows and then columns)... for eg putting the 1 st row in the place of 3 rd and 3rd in place of 4 th and 4th in place of 1st row ...something like this in columns also.. Please suggest me some ways.. thanks a lot.. with regards, boopathy. --------------------------------- [[alternative HTML version deleted]]
