Hello forum!
I am currently having trouble getting R to recognize one of my pch
characters. Here's what I have:
legend(120, 40, c("SAL-arterial", "SAL-portal", "GLP-1-arterial",
"GLP-1-portal"), bty="n", col=c("black"), pch=19:15:21:22, pt.bg="white",
pt.cex=2:2:2:2, lty=1, lwd=2, text.col="black", cex=1.3)
Now, SAL-arterial and SAL-portal should be a black circle and square,
respectively. GLP-1-arterial and GLP-1 portal should be a white circle and
square respectively.
The error message I am getting is
"Warning messages:
1: In 19:15:21 : numerical expression has 5 elements: only the first used
2: In 19:15:21:22 :
numerical expression has 3 elements: only the first used"
The SAL-arterial, GLP-1-arterial, and GLP-1-portal all are correct, however,
SAL-portal is not recognized and a small, black circle is placed there
instead of the black square that it should be.
How do I get the legend to match my data? Thanks in advance for your help!
