similar to: the underscore ("_") in variable name

don't know much about programming. But I know that it is not a good idea to assign a variable name to the name of an intrinsic constant or function. In your example, you assign the name "c" to a variable. But "c" is already the name of a function i R. In this way you are asking for trouble. -----Original Message----- From: owner-r-help at stat.math.ethz.ch

Hello, all, I'd like to propose that now that the underscore-as-assignment-operator is to be removed from R (good thing, too), that the Windows GUI should replace the underscore ``_'' with the proper assignment operator ``<-'' when you type in the underscore character. This is the current default behaviour in the ESS mode in emacs, and seems to me to be a generally good

Hi, ESS replaces "_" by "<-". How can I switch off this feature? I need to be able to type the underscore Thanks Eryk -- Witold Eryk Wolski Heidmark str 5 D-28329 Bremen tel.: 04215261837

Hello All, I''ve submitted a patch (http://dev.rubyonrails.org/ticket/8898) to enable #underscore to be reversible. I had trouble creating a class named "CRSContact", and it turns out that underscore and camelize are not reversible in cases where there are 3 or more capital letters. As there is a dependency between class name and file name I think it would be beneficial for

Hello all, I'm trying to hide files beginning with a underscore ( "_" ) and hidden files from my samba share's so i added this to my smb.conf: veto files = /_*/.*/ The section with the dot works, but the one with the underscore doesn't. I also tried /\_*/.*/ but this has the same result. Any ideas how to hide the files beginning with a underscore? Thanks, Evas

Suppose you're reading data from a file in which the column names contain underscore characters. Example: ------ start of file ----- pos_x pos_y 1.0 0.0 2.0 1.0 ------ end of file ------- Using read.table, I can read this file just fine: > data <- read.table (file="data", head=T) > data pos_x pos_y 1 1 0 2 2 1 > However, I can't

I see the uderscore "_" is not allowed in R. This make R a real drag when trying to use with SQL packages and c code. Why is the underscore not allowed and will it be allowed in a future release?

Hello, After much tinkering I managed to build packages using the 64bit version of R with the help of hints from http://www.murdoch-sutherland.com/Rtools/ and http://www.stats.ox.ac.uk/~ripley/Win64/W64porting.html and R-admin Manual. But a hack was required, and this seems to be related to a comment about underscores at the end of the second reference above (but this comment is about FUTURE

Bill Venables expected howls of protest about deprecation of underscore for assign. Here's my one-and-only howl on this point: (1) I don't like <- as an assignment operator, because it creates an ambiguity with comparisons: I can write "x+1", "x-1", "x<1" but not "x<-1". However, I guess it's a bit much to expect the entire R/S

I am working with Sweave and would like to print out into my latex document the result of the R command version$platform So what I first tried in my .Rnw document was \Sexpr{print(version$platform)}. However, the output from this command is the string "x86_64-apple-darwin10.8.0" (without the quotes). This contains an underscore, which is a special character in tex and so I get an error

This is a question that I should have sent to 'ess-help', but I take my chances... In 'NEWS' (1.9.0) I read the good news o Underscore '_' is now allowed in syntactically valid names, and make.names() no longer changes underscores. Very old code ... but when I try it in emacs (ESS 5.1.24), my '_' are changed to ' <- '! What can I do?

The Agile book mentions that using an underscore to break up words is the ''preferred'' method, but later says that you''ll have trouble using them in many-to-many association tables. What are people doing? It sounds like less of a hassle to cram my words together (cablepair vs cable_pair) and enjoy the native many-to-many handling. Or maybe I just answered my own

I found writing the following default method the for the generic function "julian" causes R to crash. julian.default <- function(x, ...) { x <- as.Date(x) NextMethod("julian", x, ...) } Here is a test example > m <- as.Date("1972-09-27") + 0:10 > m [1] "1972-09-27" "1972-09-28" "1972-09-29"

I have a big contingency table, approximately of size 60*2*500*500, and I need to count the number of cells containing a count of 1 for each of the factors values defining the first dimension. Here is my attempt: tab1<-with(pisa1,table(CNT,GENDER,ISCOF,ISCOM)) tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0)) tab3<-apply(tab2,1,sum) Computing tab2 is very slow. Is there a faster

The function "substitute" seems to fail to make a genuine substitution, although the printed verision seems fine. Here is an example. > m <- substitute(Y <- function(x) FUN(x+1), + list(Y = as.name("y"), FUN = as.name("sin"))) > m y <- function(x) sin(x + 1) > eval(m) > y function(x) FUN(x+1) However the story doesn't end there.

I am using ms sql server and want to configure RoR such that it does not convert the given table name (example: rubyonrails) to ruby_on_rails. I set @@pluralize_table_names = false, so that it does not pluralize the table names but cannot find the config setting which will force it not to put underscore between words in a table name. thanks in advance, -- avinash -- Posted via
