what is the faster way to search for a pattern in a few million entries data frame ?
Hi Fabien, I was going to send this last night, but I thought it was too simple. Runs in about one millisecond. df<-data.frame(freq=runif(1000), strings=apply(matrix(sample(LETTERS,10000,TRUE),ncol=10), 1,paste,collapse="")) match.ind<-grep("DF",df$strings) match.ind [1] 2 11 91 133 169 444 547 605 734 943 Jim On Mon, Apr 11, 2016 at 5:27 AM, Fabien Tarrade

fast way to search for a pattern in a few million entries data frame
Hi there, I have a data frame DF with 40 millions strings and their frequency. I am searching for strings with a given pattern and I am trying to speed up this part of my code. I try many options but so far I am not satisfied. I tried: - grepl and subset are equivalent in term of processing time grepl(paste0("^",pattern),df$Strings) subset(df,

Underscores in package names
I do not follow you Gabriel. Package name must not use digit numbers. Tarbal will use them, taken from the DESCRIPTION file, version field. That's why I consider the weird case name you presented as irrelevant, and not to be considered.

Underscores in package names
Won't it be better to have a convention that allows lowercase, dash, underscore and dot as only valid characters for new package names and keep the ancient format validation scheme for older package names? This could be implemented by a single function, taking a strictNaming_b_1 parameter which defaults to true. Easy to use, and compliance results will vary according to the parameter value,

Vacation use different SMTP server
Thanks for idea but it won't work for me as 'internal domains' can be anything, including gmail.com (and i don't know which of them are really internal/local, this is decided by sending SMTP everytime something is sent, based on MX records). Problem is that Dovecot/Sieve is using wrong SMTP server (one used for receiving e-mails which should NEVER be used for sending [and

share with no authentication
Hello, I got this problem: I want to mount a directory without providing a login/password [indicaf$]. I thought that "guest ok = yes" would be sufficient. But it not works. What option is the right one to open a share to everyone without a login box in windows ? Thanks.
