Dear R folks: I wonder anyone has a elegent way of doing what I need to do. I have a data frame called with four columns: V1, V2, A1 and A2: V1 V2 A1 A2 A B 1.2 2.0 A D 1.2 4.0 A C 2.4 2.2 What I need to do is to convert it into the following data frame with a new column x, where x is just the stacked up of A1 and A2 placed with respective V1 and V2 in the first two

Dear R users: My question is how to write output in a specific formate with irregular spacing? Say that I have the following DF with three columns (A-C): A B C a10 100.0 212 The objective is to write an output file such that column A occupies 1-10 spaces aligned to the left, column B occupies 11-15 spaces aligned to the right, and finally column C takes 16-25 spaces

Dear R users: I'm trying to generate a output file with fixed format using function "sprintf" in R. However, the execution time in R is very long even the toy data (smaller size df) seems to work fine. The syntax that I used is as follows: df.fmt <- sprintf("%2s%2s%2.4f", df$v1, df$v2, df$v3) write.table(df.fmt, output.name,...) The actual dataset is a df with the

Hello everybody, I'm an absolute newbe in R, so please be gentle to me. I am looking for a german map in the package maps by Becker and Wilks. After that I want to draw the German cities from world.cities of this package in the map and want to draw further a line from Berlin to Munich. Has anybody an idea? Thank you so much and sorry for the question! Best regards from Berlin, Maja!

Hi R-user, I am new with R and I have a problem with the map and mapproj fonctions : with the following code : >test_proj=mapproject(LONG_d01_vec_t1, LAT_d01_vec_t1, projection="lambert", parameters=c(30,60)) >longitude_vec=test_proj$x >latitude_vec=test_proj$y >longitude_mat=matrix(longitude_vec,ncol=e_sn_d01) >latitude_mat=matrix(latitude_vec,ncol=e_sn_d01)

Hi there, I had successfully use "MLE" function to solve my problem. Is there anyone knows how to get related information? i.e., value of likelihood function, information matrix, and etc. I know MLE-class can do it but I can not find any information tells me how to do it.

Dear R users: I have an elementary question: how to creat a vector of [A1, A2, A3...... A300]? I know c(1:300) would give 1, 2, 3, ...., 300 but not sure how to attch a A to each element. Thank you Yihsu Chen The Johns Hopkins University

Dear R users -- I think this question was asked before but there was no reply to it. I would appreciate any suggestion any of you might have. I am interested in plotting several "implicit functions" (F(x,y,z)=0) on the same fig. Is there anyone who has an example code of how to do this? Thank you Yihsu

Hello everyone, I was wondering if anyone knows how to convert the Splus mapproject( ) function for use in R, I would greatly appreciate your help. I am using the following system, R Version 1.6.1 (2002-11-01) for SunOS 5.5 and Splus Version 5.1 Release 1 for Sun SPARC, SunOS 5.5. Thanks, Helen

Dear R users; Is there a function in R that I can put "text" with proper alignments in a fixed format. For instance, if I have three fields: A, B and C, where both A and C are text with 3 characters and left alignment; B is a numeric one with 2 decimals and 3 integer space digits. How can I put the following row in a file? (note there is a space between a and 2, and after b.)

Hi, I installed the maps and mapdata libraries on my R-1.8.0 on MacOSX 10.2.8 (jaguar on a powerbook G4), and failed to make the map function work properly: R : Copyright 2003, The R Development Core Team Version 1.8.0 (2003-10-08) [...] > library(maps) > map() Error in file(file, "r") : unable to open connection In addition: Warning message: cannot open file

Dear R users; A follow-up question regarding writing to a file with fixed precision: Assuming for each column of x, I would like to have a different format, then I modify the code as: x.fmt <- apply(x, 1, function(x) sprintf("%.14f %.10f %2.5f", x)) where three different formats are %.14f %.10f %2.5f. The error message I got is "Error in sprintf(fmt, ...) : too few

dear all: Im trying to obtain maps on R, under mapdata library, but I cannot define the labels. Here is an example: library(mapdata) map("worldHires", c("portugal","spain"),ylim=c(34,46),xlim=c(-14,3.5)) axis(1,at=seq(-12,3,3)) axis(2) when I try the parameter xlab or ylab in axis, i get: parameter "ylab" couldn't be set in high-level plot()

Dear R users; I'm using ca.jo for a VECM model. Is there a way that I can get sd/p-value to see whether coefficients estimated are statistical significant? Thank you Yours, Yihsu [[alternative HTML version deleted]]

Dear R users I wonder if there is a quick way to calculate the ratio/fraction of a list/data frame. For example, if I have a data frame with two fields: "Index" and "A". I would like to know the fractions of A's within the same "Index". That is, for Index =1, three fractions will be "1/(1+2+3)=0.17", "2/(1+2+3)=0.33", and

I think it is easiest to describe what I want in terms of the concrete problem I have. I have data from a number of countries in each of which a sample of people was interviewed. In presenting the results in a forthcoming collaborative publication much emphasis will be placed on the multi-centre nature of the study. Although I suspect colleagues may do this with shaded maps I would prefer to

SUMMARY: Specific problem: I'm regridding biomass-burning emissions from a global/unprojected inventory to a regional projection (LCC over North America). I need to have boundaries for Canada, Mexico, and US (including US states), but also Caribbean and Atlantic nations (notably the Bahamas). I would also like to add Canadian provinces and Mexican states. How to put these together? General
