Jacqueline Cochran: at the time of her death, no other pilot held more speed, distance, or altitude records in aviation history than Cochran.
cdata package has an upcoming new feature called “
build_frame()” that allows for the very easy and legible entry of example
data.frames. It allows one to type in a
data.frame in a row-oriented form (much like
build_frame() we can type in a by-hand example
data.frame as follows:
library("cdata") d <- build_frame( "names", "x", "y" | "a" , 1 , 1 | "b" , 2 , 4 | "c" , 3 , 9 )
The idea is the above code looks very much like it prints (both are in a row-oriented form):
print(d) # names x y # 1 a 1 1 # 2 b 2 4 # 3 c 3 9
The number of columns was inferred from the location of the first infix operator “
|“, and all other formatting details are irrelevant.
cdata also includes a printer that prints any simple
data.frame (one containing only numeric, character, and logical values) in a ready to share format:
cat(draw_frame( data.frame(names = c('a', 'b', 'c'), x = c(1, 2, 3), y = c(1, 4, 9)) )) # build_frame( # "names", "x", "y" | # "a" , 1 , 1 | # "b" , 2 , 4 | # "c" , 3 , 9 )
This is new functionality, and I wouldn’t mind a few “test pilots” to generate some feedback before submitting this update to CRAN. Please consider filing issues on the project, or emailing me (email in the project description).
To try it you would need to install the development version of
cdata, which in
R can be accomplished by a series of command such as the following:
install.packages(c("devtools", "wrapr")) devtools::install_github("WinVector/cdata")
I also strongly recommend
R users check out
cdata‘s primary function: next generation fluid reshaping of data (more teaching materials: 1, 2, 3, and 4). It is a new thing to learn, but it takes your data engineering and data wrangling to a whole new level.
