Dear R users: I am a relatively experienced Splus user but new to R, using the version for Windows 2000. Splus allows the user to generate multiple graph pages in the graph window. For example, if you have two plot(...) commands in the script than two pages in the graph window will be created. However, when I tried this in R, the second plot will just overwrite the first plot in the graph

Dear R community: it is possible to replace NA?s in a data frame with zeroes? what should I do?

I have to store a number of vectors of the same length. I know the length but I do not know the number of vectors.

Hi all, I would like to plot some points and define the bg color of my graphics. But the bg parameter set is defined for the. whole graphic. In fact, i would like to use something like : box(bg=gray(0.9)). So, the background concerns only the plot region and not the main title, the x title and the y title. The option col for the function box() concerns the contour and there is no option

Dear all, I have to minimize a (real) function in a loop (say i in (1:1000)) and store its ``$estimate'', via l2estim<-nlm(f.minimo,c(-.01,0.1))$estimate into a vector for further analisys. Since the function's behaviour is quite peculiar (in the sense that in the simulation study it may not have a minumum), sometimes I get the the warning Error in nlm(minimo, c(-0.01, 0.1),

Hello all, Does anyone know how to make R graph the x-axis in descending order? I am all set in creating a vertical bar chart using either the plot or the xychart (in lattice), but I need the x-axis in descending order. I have tried resorting the data but apparently R automatically graphs the x-axis in ascending order. I have multiplied the data used for the x-axis by -1 and this works but now

Dear friends, I want to sort a dataset according to one or two variables in the dataset, i thought sort could do it , but failed. e.g. x <- c(2, 9, 18, 3, 2) y<-c(2,5.6,5,9,8) z<-c(21,5,5,19,7) a<-cbind(x,y,z) a x y z [1,] 2 2.0 21 [2,] 9 5.6 5 [3,] 18 5.0 5 [4,] 3 9.0 19 [5,] 2 8.0 7 I want to sort dataset a according to ascending x and descending y, How to

Hello everyone, I have a matrix of over 40000 line and about 30 columns. For my analysis I would like to add another column with ascending numbers (column header should be "order", and than 1,2,3,4 ....the end of the matrix). During my analysis I reorder them ( due to merge commands by a different column). How do I add such a column in an ascending order (or descending for what it

Dear All, here a problem I think many of you can solve in few minutes. I have a dataframe which contains values of plot id, diameters, heigths and basal area of trees, thus columns names are: id | dbh | h | g head(ipso, n=10) id dbh h g 1 FPE0164 36 13.62 0.10178760 2 FPE0164 31 12.70 0.07547676 21 FPE1127 57 18.85 0.25517586 13 FPE1127 39 15.54 0.11945906 12 FPE1127

What is the best way to sort a dataframe? For example, how would I go about sorting a dataframe (with variables V1-V5) by ascending V1, V2 and descending V3 while retaining V4 and V5. Also, is there a relatively easy way by which to re-order my columns? Thank you for your time. Marc Marc Zodet [[alternative HTML version deleted]]

Hi all, I want to order a series that is included on the second column in MCT.csv. I do but R doesn?t order, could be because is a csv? I have prove MCT<-read.csv("MCT.csv") a<-order(MCTor[,2],2,decreasing = FALSE) a<-order(MCTor[,2],1,decreasing = FALSE) or the same with sort but didn?t worked. It is suposed that a will have the ordered on ascending or descending

I have a dataset I need to sort: test.df<-data.frame(Zone=c("Floodplain", "Lake", "Shoreline"),Cover=c(50,60,70)) However, I don't want it sorted ascending/descending but in an order that I define via a vector: sort.v<-data.frame(c("Lake","Shoreline","Floodplain")) I realize I could probably just create the vector of

Hello, I wonder if there is a way to cause Xapian to order a result set purely by docid. In other words, once the result set has been determined, I'd like the results to be returned to me ordered by their docid, as opposed to by their match relevance. The problem at hand is that I'm building a search engine for a mailing list and I would like to return matches sorted by date; ordering by

I took some data from an online poll about which R GUI people used most and I am messing around with it to learn how to use qplot. Specifically I am making a horizontal bar graph and I have two questions. 1. The categories are ordered in rather strange way at least to me. It is not alphabetical or ascending/descending order of votes cast so i had to manually state the order I wanted which is

Hi, I have a data frame with variables a, b, c (character vars) and t (time var, could be represented as POSIXct or character, depending on which is most useful. The format is "yyyy-mm-dd hh:mm:ss CET"). Now, I want to sort the data frame in ascending order by a, b, c and then in descending order by t. Here's what I've got, but I'm not sure how to put the
