1 2 3 |
data |
data frame of daily constituent concentrations with date as first column |
tots |
vector of total concentrations (total PM2.5) for each day. If null, uses |
nsources |
number of sources. If null, uses number of eigenvalues of the correlation matrix greater than one. |
adjust |
method to adjust censored concentrations below minimum detection limits (MDLs). If null, uses complete case data |
mdl |
either a vector of mdls corresponding to each constituent or a matrix of mdls corresponding to each constituent and each day. |
cut |
cutoff for eigenvalues. Only used if nsources is NULL |
type |
Source apportionment method (apca or mapca) |
mons |
vector of monitors corresponding to data |
i |
monitor number (for printing) |
print |
whether to print monitors without temporal variability |
