Is there a way to check if a column is a Date in R?

WebAug 12, 2013 · The OP clearly asks for just a check: I need something to tell that the 'Date' column is a Date type. So how many date classes come with R? Exactly two: Date and POSIXt (excluding their derivatives like POSIXct and POSIXlt). So we can just check on that, and make it more robust than the answers already given: WebNov 8, 2024 · Definition: Markov chain. A Markov chain is called a chain if some power of the transition matrix has only positive elements. In other words, for some n, it is possible to go from any state to any state in exactly n steps. It is clear from this definition that every regular chain is ergodic. dickinson saison 1 streaming
