In bbTomas/tbTools: Tomas' personal mix of utilities

Description

Tomas' personal mix of utilities

Details

Mix of things that I missed in R. Matlab-like colon operator, stem plot (base plotting system), round2 with order, ifft etc.

seqM Matlab-like behaviour of colon operator or linspace for creating sequences, for-loop friendly. round2 Rounds a number to the specified order. Round half away from zero (this is the difference from built-in round function.) ifft Inverse Fast Fourier Transform (discrete FT), Matlab-like behavior.

Stem Matlab-like stem plotting function for discrete series.

isInt Returns TRUE / FALSE whether it is exactly 1 integer number (in fact, the class can be numeric but the number must be integer), non-missing isNum Returns TRUE / FALSE whether it is exactly 1 number (numeric or integer vector of length 1, non-missing) isString Returns TRUE / FALSE whether it is exactly 1 character string (character vector of length 1, non-missing) isLogical Returns TRUE / FALSE whether it is exactly 1 logical value (TRUE or FALSE), non-missing

strTrim Trim leading and trailing whitespace in character string. Way faster than str_trim() or trimws().

str_contains Find string in another string (without regular expressions), returns TRUE / FALSE. str_find Find string in another string (without regular expressions), returns indices of all occurences. str_find1 Find string in another string (without regular expressions), returns indices of the first occurence only.
