Dear All, to produce output of several columns of a data frame, I tried to use lapply and also l_ply. In both cases, I would like to print a header line containing also the name of the respective column in the data frame. For example, I would like the following lapply(data.frame(a=1:3, b=2:4), function(x) print(deparse(substitute(x)))) to produce: [1] "a" [1] "b" and

hello, I am very new to R. My current data set is a mix of values and categories. It is a geoscience data set, with values per rock sample. Case in point, each sample belongs to a lithology class, and each sample has several physical property measurements (density, porosity...). I want to be able to plot these physical properties for all samples in each lithology class. this is how i'm doing

...ced to valid R names. * `quickdf` now adds names if missing * `summarise` preserves variable names if explicit names not provided (Fixes #17) * `arrays` with names should be sorted correctly once again (also fixed a bug in the test case that prevented me from catching this automatically) * `m_ply` no longer possesses .parallel argument (mistakenly added) * `ldply` (and hence `adply` and `ddply`) now correctly passes on .parallel argument (Fixes #16) * `id` uses a better strategy for converting to integers, making it possible to use for cases with larger potential numbers of combinatio...
