...community Have just recently got back into R after a long break and have been amazed at how much it has grown, and how active the list is! Thank you so much to all those who contribute to this amazing project. My question: I am trying to calculate Mahalanobis distances for a matrix called "fgmatrix" >dim(fgmatrix) [1] 76 15 >fg.cov <- cov.wt(fgmatrix) >mahalanobis(fgmatrix, center = fg.cov$center, cov = fg.cov$cov) Then I get an error message "Covariance matrix is apparently singular" What does this mean? I can't see anything strange about the covarian...

Hi all I am not a C programmer, but I am trying to understand formatC to get consistent printing of reals to a given number of significant digits. Can someone please explain this to me? These first three give what I expect on reading ?formatC: > formatC(0.0059999, digits=2,format="fg",flag="#") [1] "0.0060" > formatC(0.59999, digits=2,format="fg",flag="#") [1] "0.60" > formatC(5.9999, digits=2,format="fg",flag="#") [1] "6.0" This seems consistent with what I read (but perhaps do not un...

Consider the following example : data(iris) attach(iris) par(bg = 'midnightblue', fg = 'yellow') plot(Petal.Length, Petal.Width, main = "Fisher's iris data", sub = "3 kinds") ##>>> gives black axis labels and titles ... ## Currently, the plot I want is produced by par(bg = 'midnightblue', fg = 'yellow', col.axis='yellow...

My question arises when I use levelplot graphics. For example, levelplot(z~x*y|fg) where fg is a factor with three levels of 'a','b','c'. The panels come out in a default order. I would like to rearrange the panels in a manner of 'c','b','a'. I used fg<-ordered(fg, levels=c('c','b','a')) But the panel...

I'm using (Linux version) xfig() within a function and then simple matplot() and matline() plots. Although I do not define any bg or fg default color, sometimes all lines in the final fig file are green. The same code works as (I) expected if I use x11() or pdf(). This is what I'm doing: I open 2 devs: xfig() dev.set(2) layout(mat1) xfig() dev.set(3) layout(mat) And then use matplot and matline...

It seems like there is no obvious way in the documentation to convert the expressions in the dots argument to a list without evaluating them. Say, if you want to have a function that prints all its arguments: > foo(abc$de, fg[h], i) abc$de fg[h] i ...then converting them to a list would be helpful. Using substitute(...) was the first thing I tried, but that only gives the *first *argument in dots. It turns out that there is a way to do this, using substitute(...()), but this does not appear to be in either the substitu...

Hello, pardon my chaotic question, but does anybody have an idea, why can't I suspend vim-enhanced-7.2.411-1.6.el6.x86_64 with a CTRL-Z, then execute few commands at my bash prompt and then get back to the vim session again with "fg"? It has stopped working at my CentOS 6.2 machine (I haven't noticed exactly when) but works fine with CentOS 5.x. I'm using PuTTY to login to both. The error message I get is: afarber at www:~> fg sudo vim test.pl ~ [1]+ Stopped sudo vim test.pl (and nothing co...

Full_Name: Frederic Schutz Version: 1.6.1 OS: Linux Submission from: (NULL) (128.250.252.193) The result of the following commands: > formatC(9.9, 1, format="fg") [1] "1e+01" > formatC(99.9, 1, format="fg") [1] "1e+02" does not seem to be coherent with what the help page says: > format: equal to `"d"' (for integers), `"f"', `"e"', `"E"', `"g"'...

...imed that: " There is no documented reason for this to work (AFAIK), so again, I would guess this is a side-effect of the implementation, and not a API feature you should rely on. This is somewhat borne out by the following: > foo <- function(...) substitute({...()}) > foo(abc$de, fg[h], i) { pairlist(abc$de, fg[h], i) } > foo(abc$de, fg[h], , i) # add a missing argument for extra fun { as.pairlist(alist(abc$de, fg[h], , i)) } which is not something you would expect to see at the user level. So my recommendation: don't use ...() and pretend that you never disco...

Dear all, I am exporting to latex a dataframe via xtable(Sweave). My dataframe includes 4 rows and 4 columns. The first two rows containing real values(e.g. a laboratory parameter's mean value), and the two rows at the bottom containing only integers (number of cases). using display=c('fg','fg','fg','fg') as an argument to xtable I tried to reach my goal, of presenting the table with numbers formatted with decimal paces in the upper rows, but with the numbers in the lower rows as integers (without superfluous commas and decimal places), as shown in the ex...

I'm trying to install R on a Red Hat 3.0.3 system, but cannot seem to get dyn.load() to fuction. The configure script says: checking for dlopen in -ldl... no And compiling fails at ../lib/libunix.a Any suggestions? What should I do to be able to use dyn.load()? I cannot upgrade the system to a higher version of Red Hat, but I will probably get away with installing some new

I probably need to be more specific. What confuses me is not the use of substitute, but the parenthesis after the dots. It clearly works and I can make guesses as to why but it is definitely not obvious. The following function gives the same final result but I can understand what is happening. dots <- function (...) { exprs <- substitute(list(...)) as.list(exprs[-1]) } In the

I'm writing a load of output to a file using cat(...), but I can't work out how to turn off scientific notation for small numbers. When I originally tried this a while a go I ended up building up a string variable, which is rather clumsy...
