I have a calculate field (called TOTAL) on Tableau which is connected to R studio to create outputs through R (the R code is written inside the Calculate Field). The R code has a function that returns a bunch of 100 and 50 in a function passing .arg's from Tableau, and the number ...
如果说tapply()和ddply()是两把不错的斧头,那aggregate()函数堪比一把金刚钻,使用起来非常灵活,极大方便了分组计算工作。 格式1: aggregate(x, by, FUN, ...) #x为数据集中需要计算的字段 #by为分组依据 #FUN为需要向分组数据应用的函数 格式2: aggregate(formula, data, FUN, ...) #formula为数据公式,...

My favourite use of aggregate with a base function is getting the last day of each month in a series of dates. To do so, one can use the following code (assuming your dates are stored in a “YYYY-MM-DD” format as strings or as Date): dates <- data.frame(date = as.Date("2001...
