اقرأ أكثرThe aggregate function presents its output summarized in a data frame-like unpacked SciDB 1-d array with the unpack=TRUE option set. This format is the most convenient format for display and manipulation by R. Grouped aggregates may optionally be returned in multi-dimensional SciDB arrays by setting the unpack=FALSE function argument (the default).

اقرأ أكثرDoes anybody know how to aggregate by NA in R. If you take the example below a <- matrix (1,5,2) a [1:2,2] <- NA a [3:5,2] <- 2 aggregate (a [,1], by=list (a [,2]), sum) The output is: Group.1 x 2 3 But is there a way to get the output to include NAs in the output like this: Group.1 x 2 3 NA 2 Thanks 1:
اقرأ أكثرaggregate is a generic function with methods for data frames and time series. The default method, aggregate.default, uses the time series method if x is a time series, and otherwise coerces x to a data frame and calls the data frame method. aggregate.data.frame is the data frame method.

اقرأ أكثرagg = aggregate(data, by = list(data$Role), FUN = mean) This produces a table of the average salary and age by role, as below. The aggregate function The first argument to the function is usually a data.frame. The by argument is a list of variables to group by. This must be a list even if there is only one variable, as in the example.

اقرأ أكثرAggregate functions are often used to derive descriptive statistics. In base R, aggregation is achieved using the aggregate function, which according to its help page, computes summary statistics of data subsets. I wrote a post on using the aggregate function because the function was not intuitive to me (at the time I wrote the post).
