as.matrix.list: Converts a list to a matrix, padding vectors with NA to fit.
In sethmcg/climod: Bias correction and other tools for climate model output

Description Usage Arguments Details Value Examples

This function cbinds the elements of a list together into a matrix. Elements shorter than the longest element are padded with NA values to fill out the matrix. If the elments themselves are lists, a specific sub-element can be extracted by name using the element argument.

1 2	## S3 method for class 'list' as.matrix(x, element = NULL, ...)

`x`	list to be converted to a matrix
`element`	sub-element of each list to extract before converting to matrix
`...`	additional arguments (ignored; included for compatibility)

This is a convenience function intended primarily to make it easy to overplot a list of similar objects all at once using matplot. The elements are padded out to a length of N by indexing them from 1:N; this works sensibly for vectors, but may produce unexpected results if the (sub-) elements of your list are some other kind of object.

a matrix

a <- seq(5,10)
b <- rev(a)
N <- a * 100
x <- mapply(function(f,g){f + seq(g)/g}, a, N)
y <- mapply(rbeta, N, a, b)
z <- lapply(y, sort)

str(y)

matplot(as.matrix(x), as.matrix(z), pch=1)

d <- lapply(y, density, na.rm=TRUE)
matplot(as.matrix(d, "x"), as.matrix(d, "y"), type='l')
