Sys.getenv {base} | R Documentation |
Sys.getenv
obtains the values of the environment variables named by
x
.
Sys.getenv(x)
x |
a character vector, or missing |
A vector of the same length as x
, with the variable names as
its names
attribute. Each element holds the value of the
environment variable named by the corresponding component of x
(or ""
if no environment variable with that name was found).
On most platforms Sys.getenv()
will return a named vector giving
the values of all the environment variables.
Sys.putenv
,
Sys.getlocale
for the locale “environment”,
getwd
for the working directory.
## whether HOST is set will be shell-dependent e.g. Solaris' csh does not. Sys.getenv(c("R_HOME", "R_PAPERSIZE", "R_PRINTCMD", "HOST")) str(s <- Sys.getenv()) # all settings (rather do not print) ## Language and Locale settings -- but rather use Sys.getlocale() s[grep("^L(C|ANG)", names(s))]
