Dear Contributors: I have two vectors x and z, and I want to display the histograms of both vectors in the same graph, x in red bars, z in blue bars. If you have any clue on how to do that, I will be very glad to hear it!!!!!! Thanks in advance again, Juan Pablo Fededa [[alternative HTML version deleted]]

...14 249 14 I want to generate a vector containing the ratios of all the values versus all the values of the z vector. I mean a vector containing the values of 526/723, 526/110, and so on, 723/723, 723/110, and so on, and so on. Is this doable in a simple way?? Thanks in advance again, Juan Pablo Fededa

Hi all, Is there an easy way to generate an object wich will be the same matrix, but ordered by de cfp value? The data frame consists of numeric columns: "Block" "X" "Y" "cfp" "yfp" "ID" 0 524 244 213.41795 7.18482109 1 0 556 270 65.383904 9.568372661 2 0 528 316 40.789474

...0 650 f 60 100 g 70 127 i.e. to add in the third column of blue the [,2] values of red corresponding to the file with same [x,1] value of blue, adding a cero in the case that there is no [x,1] corresponding value in the red matrixes (case for row 2 of blue). Thanks in advance, juan Juan Pablo Fededa [[alternative HTML version deleted]]

Hi all, I want to make a vector with the third column of a matrix, but only for the 2+3n rows of the matrix, with n being an entire number from 0 to a million. How can I do that in an easy way? Thanks in advance, Juan Pablo [[alternative HTML version deleted]]

Dear Contributors: I have the next matrix: "X" "Y" "Z" 1 2 526 2 5 723 3 10 110 4 7 1110 5 9 34 6 8 778 7 1 614 8 4 876 9 6 249 10 3 14 I want to order the matrix from bigest Z (1110) to lower Z (14). Then I want to asign a color scale vector from blue ( bigest Z) to orange

Dear r-help contributors, I have two questions: first: I have a matrix A and a vector B. I want to make a new matrix C, which is made of the rows of A having a value included in B. Second: I have two matrixes A and B, of different dimensions. B has unique values in column 2 and A has not unique values on column 2. I want to merge this two matrixes by the values in the columns 2 of B and 2 of

Hi all, I have the next matrix: a b c 1 2 23 2 3 42 3 0 54 4 5 23 5 0 22 6 7 21 7 1 20 8 9 19 I want to filter the rows with the values of b higher than 1 in a way that leaves me the next matrix: a b c 1 2 23 2 3 42 4

Hi all, I want to invert the y axis of a plot, how can I do that in an easy way? Thanks in advance, Juan Pablo

Dear contributors: I have vector A composed of numbers wich have values equal to 1 and different to 1. I want to transform de components with a value=1 to a component of value=0, and those with a value different to1, to a value=1. Then I want to take out the components=0.
