To update settings of an existing proposal genenerator
updateProposalGenerator(
proposal,
chain = NULL,
message = F,
eps = 1e-10,
manualScaleAdjustment = 1
)an object of class proposalGenerator
a chain to create the covariance matrix from (optional)
whether to print an updating message
numeric tolerance for covariance
optional adjustment for the covariance scale (multiplicative)
The this function can be applied in 2 ways 1) update the covariance given an MCMC chain, and 2) update the proposal generator after parameters have been changed
