ping: Ping a remote server, to see if it is alive
Description
This is the classic ping, using ICMP packages. Only the
system administrator can send ICMP packages, so we call out
to the system's ping utility.
Usage
ping(
destination,
continuous = FALSE,
verbose = continuous,
count = 3L,
timeout = 1
)
Arguments
continuous
Logical, whether to keep pinging until the
user interrupts.
verbose
Whether to print progress on the screen while
pinging.
count
Number of pings to perform.
timeout
Timeout for a ping response.
Value
Vector of response times. NA
means no response, in
milliseconds. Currently NA
s are always at the end of the vector,
and not in their correct position.
Examples
Run this code# NOT RUN {
ping("8.8.8.8")
ping("r-project.org")
# }
