ggplot and xlim/ylim
...ta=mtcars,y=wt, x=qsec,xlim=c(0,30)) <-> ggplot(mtcars, aes(y=wt, x=qsec)) + geom_point() + ??? Indeed the ggplot syntax is in general more flexible and powerful and I usually rely on it in scripts. It would be nice to know how to use xlim/ylim with this syntax. Thank you in advance.

Merge data frames but prefer values in one
...at or do I have to resort to some post-processing after merge? It seems that it might be something like a "right merge" for data bases but I don't know this world at all. I would be happy to look into sqldf if that allows to do things like that. Thanks in advance. Sincerely, JiHO --- http://maururu.net

apply, lapply and data.frame in R 2.5
...apply a function on all elements of a data.frame and get a similar data.frame in return. Indeed data.frames are probably the most common object in R and applying a function to each of its columns/variables appears to me as something one would want to do quite often. Thank you in advance.

'require' equivalent for local functions
...(".GlobalEnv") && class(fun) == "function") ) { cat("Sourcing", lib,"...\n") source(lib) } } but I am really not confident with all those deparse/substitute things and the environment manipulation, so I guess there should be a better way. JiHO --- http://jo.irisson.free.fr/

Problem with Weighted Variance in Hmisc
The function wtd.var(x,w) in Hmisc calculates the weighted variance of x where w are the weights. It appears to me that wtd.var(x,w) = var(x) if all of the weights are equal, but this does not appear to be the case. Can someone point out to me where I am going wrong here? Thanks.

Incomplete ouput with sink and split=TRUE
...fidence interval: -1.5807338 -0.7316803 sample estimates: mean of x mean of y 0.4437929 1.6000000 > Is this a known bug (I'm using R 2.6.1 on OS X and Linux - FC8)? Is there an inherent reason why some portions of this output are not redirected? Thank you in advance for your help. JiHO --- http://jo.irisson.free.fr/

lapply not reading arguments from the correct environment
...the function: > fooCollumn=1 > myfun() it works but uses the value defined in the general environment and not the one defined in the function. This is with R 2.5.0 on both OS X and Linux (Fedora Core 6) What did I do wrong? Is this indeed a bug? An intended behavior? Thanks in advance. JiHO --- http://jo.irisson.free.fr/

How to get information about data dependencies?
Hello, I had a question similar to this one in the link below. http://lists.llvm.org/pipermail/llvm-dev/2015-January/080589.html In addition, if we can't get RAW dependencies information using the provided llvm tools, how would I write a pass for it? Are there any helpful resources? Thanks, Jiho -------------- next part -------------- An HTML attachment was scrubbed...

rbind-ing list
hi, i have a list of data.frame that has same structure. i would like to know a efficient way of rbind-ing it. right now, i write: n = length(temp) # 'temp' is a list of data.frames temp2 = data.frame() for (i in 1:n) temp2 = rbind( temp2, temp[[i]]) return(temp2) but this is not an efficient way since we keeping overwriting temp2. i wonder if there's faster way. thanks --

plot(......,new=T) vs. par(new=T)
...ssic but I cannot find an answer to this on the mailing list (i.e. with a google search restricted to the mailing list archive). Setting: par(new=T) plot(x,y) works but plot(x,y,new=T) doesn't while it is said in plot's help that ... arguments are passed to par. What am I missing? JiHO --- http://jo.irisson.free.fr/

Selecting rows conditionally between 2 data.frames
...this is not very practical since using apply apparently converts the data to an array and looses column titles (i.e. x$size does not work, I need to use column numbers, which I'd rather not) - I feel there is an easier, vector based way. I would welcome suggestions. Thank you in advance. JiHO --- http://jo.irisson.free.fr/

Comparing multiple distributions
...he actual repartition is important also. I know this is probably not directly R related but I have already searched around for solutions and solicited my local statistics expert... to no avail. So I hope that the stats' experts on this list will help me. Thank you very much in advance. JiHO --- http://jo.irisson.free.fr/

recommendations on use of -> operator
I have never used -> but I noticed at http://github.com/jiho/r-utils/blob/master/beamer_colors.R that some people do. In fact, the above-named code has a sort of elegance about it (except for the use of "=" for assignment...). To my eye, -> calls to mind a type of assignment that is meant to stand out. For example, perhaps it would make s...

quartz() and dpi
...fall back on high resolution PNGs. Currently it forces me to add a 'scale' argument to includegraphics in latex for those. I would rather leave the latex document alone, use extension-less file names includegraphics and decide from R wether to produce a pdf or a png. Thank you in advance, JiHO --- http://maururu.net

x,y,z table to matrix with x as rows and y as columns
