This may be impossibly simple but not finding anything that lays out in direct enough fashion. So I have a lengthy string of code and upon using ggsave (look below) produces the desired chart in My Documents folder. What would I put after this in order to have the Figure 2.png to show up on the second slide? At the moment, when I knit it says, "## Saving 7.5 x 4.5 in image".
ggsave("Figure 2.png",Figure6UnEmploymentChart)
