Hello friends!! I have two questions, and I would like that you could answer me!!! I have created a plot as plot(range(10,-10),range(10,-10),col="blue",col.axis="blue",col.lab="blue",col.main="blue",col.sub="blue"); 1?) I want that the square of plot and the lines that indicates the value -10,-5,0,5,10 have a blue colour too. 2?)It?s

I want to enter a symmetric matrix containing distances for use in the cmdscale() metric scaling function. The matrix currently sits on a file in lower triangular form looking like this: 1 AWANUI RIVER .000 2 BLENHEIM .510 .000 3 COLLINGWOOD .510 .109 .000 4 FOXTON .510 .141 .141 .000 5 GISBORNE .549 .549 .549

I have a file in fwf. It is rather large, about 40,000 rows and 40 variables (columns). I only need about 10 variables form the data set for the analysis at hand. Unfortunately, these 10 variables are not contiguous in the file, for example, the first is position 1-8, the next position 25-27, then 40. Is there a way to read the selected varaibles that I need without reading in the entire data

Dear R helpers, I need to retrieve several vectors of various types from a call to .C(), but I don't know their length in advance. Is there a way to do this without allocating an excessive amount of memory? If so, an example would be very helpful. S.

Is there any way to store the value of warnings but avoid printing them? A simplified example: > out <- c(0.2,0.3,0.4) > var <- c(2,3,4) > outcome <- glm(out ~ var, family=binomial()) Warning message: non-integer #successes in a binomial glm! in: eval(expr, envir, enclos) I don't like the warning printed, but I would like to be able to check it's value after the

I need to import several ascii files in fixed format with two different record types. The data comes from European Labor Force Surveys, wich is a household survey. The first record type is for people over 16 years, and the second much sorter is for people aged 15 or less (this record has a filler with several blanks to get the same record length). The files tipically have 160000 records, with 176

Full_Name: Emmanuel Paradis Version: 2.1.1 OS: Linux Submission from: (NULL) (193.49.41.105) read.fwf(..., header = TRUE) does not work properly since: 1/ the original header is printed on the console and not in FILE; 2/ the different 'parts' of the header should be separated with tabs to work with the call to read.table. Here is a suggested fix for src/library/utils/R/read.fwf.R:

Hi everyone, my apologies if I'm overlooking something obvious in the documentation. I'm relatively inexperienced with the (awesome) ff package. My goal is to use the read.table.ffdf() function to call the read.fwf() function and pass through the colClasses and comment.char arguments. The code below shows exactly what doesn't work for me. If the colClasses and comment.char

Dear List I have a fixed width file with variables of varying width. The help is pretty transparent for this feature, but I can't seem to figure out how I can make effective use of the package with my data. In my dataset, the first 80 columns are of width 1 followed by other variables with width larger than 1. I think the correct way to do this, by brute force, would be >

I have a text file similar to this (separated by spaces): x <- "DF12 This is an example 1 This DF12 This is an 1232 This is DF14 This is 12334 This is an DF15 This 23 This is an example " and I know the field lengths of each variable (there is 5 variables in this data set), which are: varlength <- c(2, 2, 18, 5, 18) How can I import this kind of data into R, using the varlength

Hi all, I have a matrix like this: 188556644 225588666 558888555 I try to read the table using read table but if I put sep="" I have seen it expects a white space, is there a "sep" option to read this matrix so each single number is a position of the matrix You see this matrix would be an 3x9 matrix I tried other option but also didn´t worked. If sep = "" (the

I'm finding that readLines() and read.fwf() take nearly two hours to work through a 3.5 GB file, even when reading in large (100 MB) chunks. The unix command wc by contrast processes the same file in three minutes. Is there a faster way to read files in R? Thanks!

Is there a way to handle the widths of values being written to a file using wrtite.fwf() ? For example, I used read.fwf(file, width.vector) to read a file. After making the necessary data manipulation, I want to write the data to a new file in the same width.vector format. Is there a way to specify this? Thanks in Advance Aparna [[alternative HTML version deleted]]

Need way to resize an existing graphics window. This should be applicable across platforms (as part of a package). Context: function1() draws main plot (I'm using grid), function2() adds smaller plot above main plot, but this one can sometimes overflow the original graphics window area. Thanks, Sigal
