How to identify the indices of a certain value in a vector - 2 programming examples - match function, which function & %in% operator - Reproducible R code. an ordered vector of the same length as the "index" attribute of x . Details. index is a generic function for extracting the index of objects, currently it has a default Mid level search, mid level search functions return positions in index order ( sorted). indexFindInterval, finding a sequence of exact or approximate values. But, we will get a missing value if we try to index outside the length of a vector: length(c(1:3)) ## [1] 3 c(1:3)[9] ## [1] NA. Positional indices can also involve an R
13 Apr 2018 Yes, we can find the index of an element in a vector as follows: > a <- c(3, 2, -7, -3 , 5, 2) > b <- (a==-7) # this will output a TRUE/FALSE vector > How to identify the indices of a certain value in a vector - 2 programming examples - match function, which function & %in% operator - Reproducible R code. an ordered vector of the same length as the "index" attribute of x .

The total return index is a type of equity index that tracks both the capital gains of a group of stocks over time, and assumes that any cash distributions, such as dividends, are reinvested back into the index. Looking at an index's total return displays a more accurate representation of the index's performance.
