Minor issues/typos

[tbartels163]

Thank you so much for this wonderful resource! I’d love to pay forward and share the few minor issues/typos that I spotted while working through Hands-On Programming with R.

• 5.7 choose “subelement” or “sub-element” for consistency
• 7.0.2 “indivuidually compare” --> typo in “individually”
• 8.8 “the function’s origin enviornment” --> typo in “environment”
• 9.1 “If a subtask seems complicated, try to divide it again into even subtasks that are even more simple.” --> I’m assuming delete the first “even” so that it reads “[…] try to divide it again into subtasks that are even more simple.”
• 9.3 length(unique(symbols) == 1) shouldn’t this be length(unique(symbols)) == 1 ?
• 9.3 Some of the brackets {} are highlighted in red but should probably just be black.
• Very end of 9.5: play() ## "BB" "BB" "B" ## 25 --> shouldn’t that be 5 (any combination of bars)?
• Exercise 11.7 (Calculate the Expected Value): “Solution.” header missing
• 12.1/2 function specified as “abs-sets” in the code but referred to as “abs-set” (“s” missing) in the main body of text
• 12.3 “abs_loop and change_many illustrate a characteristic of vectorized code: […]” --> change “change_many” to “change_symbols” in two instances, I think.

Thank you very much once again. I hope this is helpful :-)
