Remove sensitive cells from raster
Description
remove_sensitive
removes sensitive cells from a sdc_raster
.
The sensitive cells, as found by is_sensitive()
are set to NA.
Usage
remove_sensitive(x, max_risk = x$max_risk, min_count = x$min_count, ...)
mask_sensitive(x, max_risk = x$max_risk, min_count = x$min_count, ...)
Arguments
x |

max_risk |
a risk value higher than |
min_count |
a count lower than |
... |
passed on to |
Details
Removing sensitive cells is a protection method, which often is useful to
finalize map protection after other protection methods have been applied.
mask_sensitive
and remove_sensitive
are synonyms, to accommodate both
experienced raster
users as well as sdc users.
Value
sdc_raster object with sensitive cells set to NA
.
