How to display only the first two "plot (model)" plots in script mode?
I have a script that essentially boils down to
model <- lm(d$o ~ d$t * d$w)
plot(model)
When I run these commands interactively (RStudio) plot
will create four graphs. The user should go to the next graph by pressing enter.
Now I want to run commands in (almost) non-interactive mode and a command plot
to only display the first two plots. The user of the script will of course still need to click or press enter after the R environment displays the first and second graphics.
How could I achieve this?
Edit
It has been suggested that I am using a parameter which
(described in ?plot.lm
). However, if I change the relevant line to
plot(model, which=1)
script breaks off with
Error in box(...) : invalid 'which' argument
Calls: plot -> plot.default -> localBox -> box
In addition: Warning messages:
1: In plot.window(...) : "which" is not a graphical parameter
2: In plot.xy(xy, type, ...) : "which" is not a graphical parameter
3: In axis(side = side, at = at, labels = labels, ...) :
"which" is not a graphical parameter
4: In axis(side = side, at = at, labels = labels, ...) :
"which" is not a graphical parameter
Execution halted
Try the following:
plot(model, which=1:2).
This worked for me.
We do not know your details. But it works!
n=50
d=data.frame(o=rnorm(n,10,3),t=1:n,w=rep(c("A","B","C"),length.out=n))
model <- lm(d$o ~ d$t * d$w)
plot(model)
op=par(mfrow=c(2,2))
for(i in 1:4)plot(model, which=i)
par(op)
