Re: [R] Average of Two Matrices

What if you have over 50 matrices and you don't want to write them all out one-by-one? I know there's something really quite simple, but I haven't found it yet!... -- View this message in context: http://r.789695.n4.nabble.com/Average-of-Two-Matrices-tp860672p4126615.html Sent from the R help m

[R] "each" argument in rep (Bug?)

I have a vector of unique elements that I want to replicate a variable number of times depending on the element (lengths all > 800). However I noticed that the resulting length was not the sum of the each argument. The following example demonstrates this. I am confused as to why this works:

[R] another superscript problem

[R] truncate integers

Is there any really easy way to truncate integers with several consecutive digits without rounding and without converting from numeric to character (using strsplit, etc.)?? Something along these lines: e.g. = 456 truncfun(e.g., location=1) = 4 truncfun(e.g., location=1:2) = 45 truncfun(e.g.,

Re: [R] Rename column or row names

this isn't a whole lot different, but if x is a data.frame (and not a matrix), you could also try this: names(x)[which(names(x)=="oldname")]= "newname" -- View this message in context: http://r.789695.n4.nabble.com/Rename-column-or-row-names-tp2288122p2288183.html Sent from the R help mailing

Re: [R] create variables with indexes

Here is another way of going about it (presuming we are correct about what you are after): i=1:10 j=1:10 unlist(lapply(i, function(x) paste("X", x, j, sep="_"))) Tyler -- View this message in context: http://r.789695.n4.nabble.com/create-variables-with-indexes-tp2288119p2288171.html Sent from

Re: [R] Checking for duplicate rows in data frame efficiently

Henrique is correct; entering duplicated(df) will return an index of TRUE or FALSE for every row. TRUE indicates a duplicated row. df[duplicated(df),] # shows which rows are repeated df[-duplicated(df),] # shows which rows are unique -- View this message in context: http://r.789695.n4.nabble.

Re: [R] Want to exclude a column when using sample function

It's not really clear what the structure of your data is, nor how exactly you are sampling it (you need to provide an example), but you could try adding this to the end of your sample command (if the result is a data.frame or matrix): [,-1] Tyler -- View this message in context: http://r.789695
