subsetsites.Hst.ls {widals}

Site-Wise Extract Space-Time Covariates

Description

Extract space-time covariates by site

Usage

subsetsites.Hst.ls(Hst.ls, xmask)

Arguments

Hst.ls

Space-time covariates. A list of length \tau, each element should be a n x p_st numeric matrix.

xmask

Which sites to remove from Hst.ls. A boolean vector of length n, or a vector of spacial indices.

Value

Space-time covariates. A list of length \tau, each element a c x p_st numeric matrix, where c is the number of TRUE's in boolean xmask, or length of index xmask.

Examples

	
tau <- 70
n <- 28

Hst.ls <- list()
for(i in 1:tau) { Hst.ls[[i]] <- matrix(rnorm(n*4), nrow=n) }

subsetsites.Hst.ls(Hst.ls, c(1,3,10))


subsetsites.Hst.ls(Hst.ls, c(TRUE, TRUE, rep(FALSE, n-2)))
