ls{size,type,class,data} ,Q&D tools to get info about various collections of objects
askrm , an interactive tool to apply a function to each selected object
seqle, reverse.seqle , extension of rle to find linear sequences
resave , add objects to an existing .Rdata file   short , combine Unix 'head' and 'tail', with options
mystat , get basic statistics of a vector or array
splatnd , a tutorial bit of code on how to create your own zero-argument operators

Description: Functions for performing quick observations or evaluations of data, including a variety of ways to list objects by size, class, etc. In addition, functions which mimic Unix shell commands, including 'head', 'tail' ,'pushd' ,and 'popd'. The functions 'seqle' and 'reverse.seqle' mimic the base 'rle' but can search for linear sequences. The function 'splatnd' allows the user to generate zero-argument commands without the need for 'makeActiveBinding' .

Description: A set of tools the author has found useful for performing quick observations or evaluations of data, including a variety of ways to list objects by size, class, etc. Several other tools mimic Unix shell commands, including 'head', 'tail' ,'pushd' ,and 'popd'. The functions 'seqle' and 'reverse.seqle' mimic the base 'rle' but can search for linear sequences. The function 'splatnd' allows the user to generate zero-argument commands without the need for 'makeActiveBinding' .

The function 'splatnd' allows the user to generate zero-argument commands without the need for 'makeActiveBinding' .  Functions provided to convert from any base to any other base, and to find the n-th greatest max or n-th least min.  In addition, functions which mimic Unix shell commands, including 'head', 'tail' ,'pushd' ,and 'popd'.

Description: The solution to some common problems is proposed,
as well as a summary of some small functions. In particular,
it provides a useful function for some problems in chemistry.
For example, monoa(), monob() and mono() function can be used
The ggpng() function can save the PNG format with transparent background.
The period_table() function will show the periodic table. Also the
show_ruler() function will show the ruler.
I also provide the symb() function to generate multiple symbols at once.
The csv2vcf() function provides an easy method to generate a file.
