Miscellaneous functions useful for teaching statistics as well as actually practicing the art. They typically are not new methods but rather wrappers around either base R or other packages.

The compound growth rate indicates the percentage change of a specific variable over a defined period. It is calculated using non-linear models, particularly the exponential model. To estimate the compound growth rates, the growth model is first converted to semilog form and then analyzed using Ordinary Least Squares (OLS) regression. This package has been developed using concept of Shankar et al. (2022)<doi:10.3389/fsufs.2023.1208898>.

Functions for performing quick observations or evaluations of data, including a variety of ways to list objects by size, class, etc.  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' .  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'. Various other goodies included as well.

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 
     to calculate The pH of weak acid/base. 
     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.
     The show_color() function is funny and easier to show colors.
      I also provide the symb() function to generate multiple symbols at once.
     The csv2vcf() function provides an easy method to generate a file.
     The sym2poly() and sym2coef() function can extract coefficients from 
     polynomials.
