Dear all, I am trying to manually re-sort rows in a number of tables. The rows aren't sorted on any particular values but are simply ordered by user choice (as shown by the row numbers in the code). I have been able to carry out each re-arrangement without the use of the 'for' loop, but cannot seem to successfully execute the statements when incorporated into the loop. The code I have

Dear all, I have produced a barplot and wish to alter the axes a little. In place of the variable names appearing on the x-axis, I'd like to have the numbers 1986 to 1995. I have tried using the argument xlim=c(1986,1995) in the barplot command but receive: "Error in plot.window(xlim, ylim, log = log, ...) : invalid 'xlim' value" Also, on the y-axis, the values are

Dear all, I'm trying to assign a name to the fourth column whilst using 'assign', but keep encountering errors. What have I done wrong?! > assign(colnames(c(paste("arunoff_",table_year, sep="")[4]), "COUNT")) Error in if (do.NULL) NULL else if (nc> 0) paste(prefix, seq_len(nc), : argument is not interpretable as logical Hope someone is able

Dear all, I have a data frame of three columns, which I have sorted by Latitude as follows: > test2[60:80,] Latitude Longitude Sim_1986 61948 85.25 -29.25 2.175345 61957 85.25 -28.75 8.750486 61967 85.25 -28.25 33.569305 61977 85.25 -27.75 23.702572 61988 85.25 -27.25 26.488602 62000 85.25 -26.75 23.915724 62012 85.25 -26.25 25.055082 62027

Dear all, I think I'm nearly there in writing R code which will read in files with two variable parts to the file name and then assigning these file names to objects, which also have two variable parts. I have got the code running without encountering errors, however, I receive 50+ of the same warnings: 1: In assign(paste("Fekete_", index$year, index$month, sep = ""),

Dear all, I am attempting to add row and column names to a series of tables (120 in total) which have 2 variable parts to their name. These tables are created as follows: # Create table indexes index <- expand.grid(year = sprintf("%04d", seq(1986, 1995)), month = sprintf("%02d", 1:12)) # Read in and assign file names to individual objects with variable name components

Hi all, how can I divide two tables of the same dimension so that all names are preserved, ie do not become NA? I have "tab1" and "tab2", each having names in the first column. I want "tab3" with the same names and values "tab1/tab2". Thanks, Serguei

Hi all, I am not exactly fluent in R and I got stuck with this. I would like to compare each elements of a vector A with any of the elements in Vector B. For some reasons it does not work. > StartDate = as.Date("01/10/2007", "%d/%m/%Y") > TimeSpan = seq(StartDate, by = 'days', length = length(myAverageCWVs$X1986)) > TickLabels = c("2007-10-01",

Dear R Users, I'm trying to use the reshape package to 'melt' my gridded data into column format. I've done this before on individual files, but this time I'm trying to do it on a directory of files (with variable file names) - therefore I have to also use the 'assign' command. I have come up against a couple of problems however and am therefore seeking advice... >

Hello All, I have multiple "list of lists" in the form of Mylist1[[N]][[K]]$Name_i, with N=1..6, K=1..3, and i=1..7. Each Name_i is a matrix. I have 30 of these objects Mylist1, Mylist2, ... I would like to merge these lists by each Name_i using rbind, but I couldn't figure out how to do it. What I want at the end is a single "list of lists", again in the form of
