You can leave your script as it was and use source()'s
print.eval=TRUE or echo=TRUE arguments to get the
autoprinting done as it is at the command line
(echo=TRUE also prints the commands).
E.g., for the file "/tmp/x.R" containing the 2 lines
d <- mtcars[,c("am","gear","hp","mpg")]
summary(lm(data=d, mpg~.))
I get
> source("/tmp/x.R")
or
> source("/tmp/x.R", echo=TRUE) # this is the only line I typed
> d <- mtcars[,c("am","gear","hp","mpg")]
> summary(lm(data=d, mpg~.))
Call:
lm(formula = mpg ~ ., data = d)
[... many output lines elided ...]
F-statistic: 34.83 on 3 and 28 DF, p-value: 1.377e-09
or
> source("/tmp/x.R", echo=FALSE, print.eval=TRUE) # only line I typed
Call:
lm(formula = mpg ~ ., data = d)
[... many output lines elided ...]
F-statistic: 34.83 on 3 and 28 DF, p-value: 1.377e-09
