mean function

Arithmetic Mean

The arithmetic mean of an expression. methods

## S3 method for class 'Expression'
mean(x, trim = 0, na.rm = FALSE, ...)

Arguments

• x: An Expression object.
• trim: (Unimplemented) The fraction (0 to 0.5) of observations to be trimmed from each end of $x$ before the mean is computed.
• na.rm: (Unimplemented) A logical value indicating whether missing values should be removed.
• ...: (Unimplemented) Optional arguments.

Returns

An Expression representing the mean of the input.

Examples

A <- Variable(2,2)
val <- cbind(c(-5,2), c(-3,1))
prob <- Problem(Minimize(mean(A)), list(A == val))
result <- solve(prob)
result$value
