Compressing descriptions using camelcase


For long descriptions, sometimes it is beneficial to compress them into camelcase to improve readability. This is especially valuable when viewing descriptions that are labels on x or y axes.

Camelcase is a method that some programmers use for writing compound words, where spaces are first removed, and then each word begins with a capital letter. It is also a way of conserving space.

To accomplish this, we can write a function called .simpleCap, which performs this function. To illustrate how it works, we will pass it a two element character vector c("A certain good book","A very easy book"), and observe the results.

Custom function to map to camelcase

This is a simple example use of this function that maps the two character vector c("A certain good book", "A very easy book") to camelcase. This vector is mapped to two new elements:

[1] "ACertainGoodBook", and  [2] "AVeryEasyBook" 
 
# change descriptions to camelcase maybe append to itemnumber for uniqueness...
