check.1.integer {spatstat.utils} | R Documentation |
These utility functions check whether a given argument is a single value of the required type.
check.1.real(x, context = "", fatal = TRUE) check.1.integer(x, context = "", fatal = TRUE) check.1.string(x, context = "", fatal = TRUE)
x |
The argument to be checked. |
context |
Optional string specifying the context in which the argument is checked. |
fatal |
Logical value indicating what to do if |
These functions check whether the argument x
is a single
atomic value of type numeric
, integer
or
character
.
If x
does have the required length and type, the result
of the function is the logical value TRUE
.
If x
does not have the required length and type,
then if fatal=TRUE
(the default) an error occurs,
while if fatal=FALSE
a warning is issued and the
function returns the value FALSE
.
A logical value (or an error may occur).
