pdf() basically works the same as postscript(). Both produce vector graphics output. The default settings can be checked with:

pdf.options()

## $width
## [1] 7
## 
## $height
## [1] 7
## 
## $onefile
## [1] TRUE
## 
## $family
## [1] "Helvetica"
## 
## $title
## [1] "R Graphics Output"
## 
## $fonts
## NULL
## 
## $version
## [1] "1.4"
## 
## $paper
## [1] "special"
## 
## $encoding
## [1] "default"
## 
## $bg
## [1] "transparent"
## 
## $fg
## [1] "black"
## 
## $pointsize
## [1] 12
## 
## $pagecentre
## [1] TRUE
## 
## $colormodel
## [1] "srgb"
## 
## $useDingbats
## [1] TRUE
## 
## $useKerning
## [1] TRUE
## 
## $fillOddEven
## [1] FALSE
## 
## $compress
## [1] TRUE

However, there is no equivalent to setEPS(). Therefore, we need to provide all device specifications and changes of the default settings directly in the device setup call:

pdf("test_la_line.pdf", onefile = TRUE, bg = "white", 
    family = "Times", width = 6.83)

print(xyplot(1:10 ~ 1:10, type = "l", lwd = 96/72 * 2))

invisible(dev.off())
