Hi all, I have R installed on a box, which is running on a machine with 16 core and Redhat - Linux. I am handling huge (size of dataset will be 5 GB) dataset. Lets assume that my data is in the form of structured (multiple) logs. I access the data by using all.files(). Since by default basic version of R utilizes single core, the processing of my analysis code is taking too much time. I got to

Greetings! I'm have a hard time working with some data I imported from a baseball database. Several of the database columns have numbers in them (2B, 3B), and when I try to use these vectors from the data frame, I get syntax errors, probably because it's interpreting the name as a number: > show(batting2005) playerID yearID stint teamID lgID G AB R H 2B 3B HR RBI SB CS BB

Hi, My standard Linux desktop is based on a personal blend of CentOS 7 with KDE 4.14 and various add-ons from third-party repositories like EPEL and Nux-Dextop. After a brief stint on OpenSUSE Leap 15.0, this is what I use on my workstation and on my laptop. And this is also what I install on my client's machines, just like I did in our local school's computer room. I'm currently

The double quotes are required by SQL if a name is not of the form letter-followed-by-any-number-of-letters-or-numbers or if the name is a SQL keyword like 'where' or 'select'. If you are doing this from a function, you may as well quote all the names. -Bill On Fri, Oct 2, 2020 at 6:18 PM Philip <herd_dog at cox.net> wrote: > The \?2B\? worked. Have no idea why. Can

Hi Philip, You've probably realized by now that R doesn't like column names that start with a number. If you try to access an R-dataframe column named 2B or 3B with the familiar "$" notation, you'll get an error: > library(DBI) > library(RSQLite) > con2 <- dbConnect(SQLite(), "~/R_Dir/lahmansbaseballdb.sqlite") > Hack12Batting <-

This is really a feature of SQL, not R. SQL requires that you double quote column names that start with numbers, include spaces, etc., or that are SQL key words. E.g., > d <- data.frame(Order=c("sit","stay","heel"), Where=c("here","there","there"), From=c("me","me","you")) >
