Registration Link: http://bit.ly/matygo-rails-beginners-jan-2012 Our classes are fully online but are quite interactive. This is how it works: 1. Weekly live group video workshop led by an instructor that clarifies and builds upon the week’s homework and provides personal guidance. We integrated Google Hangouts, so this is a true group video classroom (limited to 9 students) with screen sharing, whiteboarding, and more. 2. Private discussion forums, assignments, file and resource sharing. This...

I am trying to import a .txt table in my class on R and for some reason, the header gets altered and I can no longer read the data.

...e.g. Stats 1 Fall2009 J. Smith. I have a frame for all instances of a course, e.g. stats 1 in the last 5 years, that looks like SIDN TERM GRADE INST where SIDN is a Student ID Number, TERM is a factor that gives the quarter and year a course was offered, GRADE is a 0-4.3 grade and INST is the instructor, again as a factor. Course offerings are determined by the TERM and INST. That is one inst. assigned grades to all the students they were responsible for that term. Multiple instructors may have taught the same term. For every course offering I would like to normalize the GRADE: Z<- (GRADE...

I want to populate one table in a DB from another table so that the user does not need to enter the same information twice. I have a registration table that is populated when a user creates an account. Later I have a form that uses a different table, but contains most of the same info as the registration table. I would like that table to be prepopulated by the registration table before the user

Hello R users, I have a basic "computer programing" question. I am a student currently taking a course that uses Fortran as the main programming language, but the instructors are open to students using any language they are familiar with. I have used R previously, and am wondering if there is any benefit to my learning Fortran, or whether I should stick with R for this class. Any advice? Are there clear benefits to using Fortran, or things Fortran can do that R can...

I've got 20 windows desktop machines in a lab on a samba network. Throughout the semester instructors usually find some software they want installed. Has anyone come up with a good way to push out files to all these machines? I've seen demos of software management in Windows 2003. Or any inexpensive commercial product for software management for networks that are not Windows AD? I think I'...

I am possibly going to be sent for my RHCE training. Looking at https://www.redhat.com/courses/rh300_rhce_rapid_track_course_and_rhce_exam/details/ I am thinking the concepts do not look difficult at all, having a manual and instructor makes this look fairly easy actually. The only thing that looks important to take outside of this would be rh253 if I wasn't interested in taking the elementary courses. Anyone done the VT courses? To fit within the budget and get what I think I need, I might take the rh253vt before the rh300...

I am taking a behavioral stats graduate class and the instructor is using SPSS. I'm trying to follow along in R. Recently in class we started working with scales and survey data, computing Cronbach's Alpha, reversing values for reverse coded items, etc. Also, SPSS has some built in functionality for entering the meta-data for your survey, e.g. the poss...

The rates between 384Kbps and 1.5Mbps should be shared among all users. Each user should always be able to get at
