Hi! I had a database with some variables in sequence. Let me say: TX01, TX02, TX03 and TX04. But I need to run some regressions changing the variables... so: variable <- paste("TX0", 1:4, sep="") for(i in 1:4){ test[i] <- lm(variable[i] ~ INCOME, data=database) } But doesn't work... lm tries to find a variable inside database named variable[i] ... Suggestions?

Hello, I have a question about multichannel and the load-balancing algorithm. What kind of algorithm is it? (Roud-robin, dynamic round-robin, ...) What are the arguments the algorithm compute to load-balance the network traffic on the interfaces? I already know that if a 10Gb/s interface and a 1Gb/s interfaces are in the multichannel connection the 1Gb/s one will be ignored until the 10Gb/s goes

Is there a way to import a data frame into a workspace? I created a data frame and from my understanding, a data frame is a type of object, and that the workspace stores the current session's objects. Wondering why my data frame is not showing up...

Dear Sirs: I am not yet a user of R. My background includes the use of (Turbo) Pascal for scientific analysis of underwater acoustics problems (e.g. sound ray tracing and array gain in directional noise fields.) I have become interested in the following type of problem: (1) select , say, 1000 random locations within the continental United States; (2) characterize (statistically) the

Hello, Another French student in the rsync mailing list. I have been working on rsync this year for a documentation project for school and I would like to give some comment about rsync block size optimization first, and then to submit a way to make rsync choose by itself the optimal blocksize when updating a large number of files. Well, the first comment: during my work, I wanted to verify

Dear R experts, Suppose I have an data frame likes this: > example <- data.frame(age=c(1,2,3, 4,5,6), height=c(100,110,120,130,140,150), disease=c(TRUE, TRUE, TRUE, FALSE, FALSE, FALSE)) > example age height disease 1 1 100 TRUE 2 2 110 TRUE 3 3 120 TRUE 4 4 130 FALSE 5 5 140 FALSE 6 6 150 FALSE Is there anyway to compare the age and

Hi! In Windows the "win.print" function allows plotting directly to a printer (or copying an open device to the printer). This is very convenient to quickly print a plot once it looks good. Is there an equivalent function under Linux? For example through CUPS, IPP, LPD or other ? Obviously with a printer on the parallel port one could write postscript("/dev/lp0") but what

Hi, I have a silly question regarding the usage of two commands: read.table and gregexpr： For read.table, if I read a matrix and set header = T, I found that all the dash ("-") becomes dots (".")

Hi, Is there a configuration element that would allow me to change the dot-lock name for the user's /var/mail inbox when it is locked? dovecot (correctly) acquires <username>.lock, but I'm having a problem with procmail where some obscure code path is preventing procmail's acquisition of a lock when it's that default name in /var/mail.
