[R] Save a graph file use jpeg(file=file)

[Sorkin, John]

Tim
Thank you for your suggestion. The problem with your suggestion is that the copied image is low resolution, 96dpi. Saved files can have higher resolution.
Thank you
John

The simple solution for Windows is to use (windows icon) + shift + s. You then select a portion of your screen and it gets copied to your clipboard. You can then paste that into your document. Of course this will not work if it is important that the reader is able to rotate the graphic.

Subject: [R] Save a graph file use jpeg(file=file)

[External Email]

I am trying to create a 3-D graph (using scatter3d) and save the graph to a file so I can insert the graph into a manuscript. I am able to create the graph. When I run the code below an RGL window opens that has the graph. The file is saved to disk after dev.odd() runs. Unfortunately, when I open the saved file, all I see is a white window. Can someone tell me how to have the file so I can subsequently read and place the file in a paper? The problem occurs regardless of the format in which I try to save the file, e.g. png, tiff.


x <- 1:10
y <- 2:11
z <- y+rnorm(10)
ForGraph<-data.frame(x=x,y=y,z=z)
ForGraph

gpathj <- file.path("C:","LAL","test.jpeg") gpathj jpeg(file = gpathj) par(mai = c(0.5, 0.5, 0.5, 0.5)) scatter3d(z=ForGraph$x,
         y=ForGraph$y,
         x=ForGraph$z,
         surface=FALSE,grid=TRUE,sphere.size=4
         ,xlab="Categories",ylab="ScoreRange",
         zlab="VTE Rate (%)",axis.ticks=TRUE)
dev.off()


Thank you,
John
