How to assess object names within a function in lapply or l_ply?
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"

tips for looping over a category for beginner
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...
