Use dump or write? or what?
...)
two_sample_ttest <- t.test (tempA, tempB, var.equal = TRUE)
welch_ttest <- t.test (tempA, tempB, var.equal = FALSE)
dump (two_sample_ttest, file = "dumpdata.txt"", append=TRUE)
ttest_results <- file.append (ttest_results, two_sample_ttest)
Any suggestions,

reshape::rename package unable to install !?!
...ng, BUT when I
tried to reinstall 'reshape' or 'reshape2' I COULDN't. Is there a way
to get over this hurdle with reshape or is there another command I can
use. I am stuck because my programs up to this point used 'rename'
and now I have to redo some work.

Unusual separators
...., sep=" \t", ...) but got an error that
said something like 'only one byte separators can be used.
I have thought about using a gsub to 'swap out' the "space + tab" and

Which is more efficient?
...colB <- temp [ , k ]
ttr <- t.test ( colA, colB, var.equal=TRUE)
tt_pvalue [ i ] <- ttr$p.value
}
}
}
--------------------------------
I am a novice writer of code and am interested to hear if there are
any (dis)advantages to one way or the other.

Data.frame Vs Matrix Vs Array: Definitions Please
Hi All,
I am learning R and having a little trouble with the usage and proper
definitions of data.frames vs. matrix vs vectors. I have read many R
tutorials, and looked over ump-teen 'cheat' sheets and have found that
no one has articulated a really good definition of the differences

Opening Screen
Greetings All,
What is the procedure to make the open screen for R silent. I would
to have my opening screen in Ubuntu 10.04 linux open to an empty
terminal. Instead of the list of licenses and version of R that is
being run. By the way, I am using RStudio as well. I have entered
the following lines into my '/home/user/.Rprofile' but this is more of
a 'cheat' ;) to me.

I have two sets of data that I would like to investigate. The first is

here goes.)/
