This function returns the rest of the string from where it found the first occurrence of a specified character, otherwise it returns FALSE. Thanks for the listings stata language definition! Just FYI, to use the \lstset example settings at the end, \setmonofont requires the fontspec package, which in turns requires running XeTeX or LuaTeX. Often we want to visualize the distribution of data across several subgroups. See something missing or incorrect? Then help us fix it. int(x) returns the integer obtained from dropping the digits after the decimal point of number x. Create a new IPython 'profile' with. If it is a negative number, this function extracts from the end of the string. – Nick Cox Mar 4 '14 at 12:21 add a comment |. unique, which is useful if you need to generate unique elements, given a vector containing duplicated character strings. com When working with binary strings, one can find the first or last location of the binary 0 using strpos(s, char(0)) or strrpos(s, char(0)). For example, [U] 26 Overview of Stata estimation commands [R] regress [XT] xtreg The first example is a reference to chapter 26, Overview of Stata estimation commands, in the Users Guide; the second is a reference to the regress entry in the Base Reference Manual; and the third is a reference to the xtreg entry in the Longitudinal-Data/Panel.
