what is the function naming convention?
...s (etc) - using dots and intercapping: as.Date, julian.Date, toString.default (etc) So, an entire zoo of function names. Did I miss a system, or is it arbitrary (within the set of accepted characters) ? What is the best way to name one's own functions?

A categorized list of R functions
...e not elegant, but seems to work (however: test it!). Column order can be changed by changing the printing order of newhits[ ,1] ,2 and ,3. In addition, Liviu Andronic's suggestion to use the package "sos" (strange name, but good tip) seems also interesting.

Reading multiple files
Hi, I have 35 data files for reading. I would like get a program for performing reading of 35 files at once. All are of the type: Dados1.raw, Dados2.raw and so on.

tip: large plots
Hi all, I'm working with a bunch of large graphs, and stumbled across something useful. Probably many of you know this, but I didn't and so others might benefit. Using pch="." speeds up plotting considerably over using symbols. > x <- runif(1000000) > y <- runif(1000000) > system.time(plot(x, y, pch=".")) user system elapsed 1.042 0.030 1.077

categorized complete list of R commands?
every time I read the R release notes for the next release, I see many functions that I had forgotten about and many functions that I never knew existed to begin with.

"Empty" DNS entry, no A record, can't delete or update
Hi, I am running Samba 4.1.0 with Bind 9.8.4 and I am struggling with an "empty" DNS entry. I used Microsofts DNS MMC to add an A record to one of my zones, later deleted this entry because I wanted to move the record to another zone. After I moved it backed the A record (and the PTR) was invisible in the MMC. nslookup still works for the IP and hostname from the PDC and other hosts

Identify does sort the locations
Hi, Using identify function, I think I should get the index of the selected points in the order I clicked them. This is what I read in the help. But I feel they are ordered. Please let me know what I missed. In the following example, I clicked on the points labelled 7, 5 and 1, but I get 1, 5, 7 as output. > set.seed(0); x = rnorm(10); y = rnorm(10); plot(x,y); text(x, y, > seq(x));
