I get this error when trying to plot:

plot(SG, aes(fill=AGE, y=OC, x=AGE)) +
geom_blank() + theme_bw() +
theme(panel.grid.major = element_blank(), panel.grid.minor =
element_blank()) +
geom_bar(position="dodge", stat="identity", colour="black", size=.3) +
geom_errorbar(aes(ymin=OC-SE, ymax=OC+SE), width=.1, size=.1, # Width of
the error bars
position=position_dodge(0)) +
xlab("Crop Age") + ylab("SOC (%)") + ggtitle("") +
expand_limits(y=c(NA, 4.5))

the error message is: Error in plot(SG, aes(fill = AC, y = OC, x = AC)) +
geom_blank() :
non-numeric argument to binary operator

Any help is appreciated.

A follow-up question now that you have resolved this issue. I am trying to
draw multiple linear regressions on this plot. I have the equations that I
want to draw but not sure how to do this. I have read a few other threads
on here and still unsure where to start.

plot(SG, aes(fill=AGE, y=OC, x=AGE)) +
geom_blank() + theme_bw() +
theme(panel.grid.major = element_blank(), panel.grid.minor =
element_blank()) +
geom_bar(position="dodge", stat="identity", colour="black", size=.3) +
geom_errorbar(aes(ymin=OC-SE, ymax=OC+SE), width=.1, size=.1, # Width of
the error bars
position=position_dodge(0)) +
xlab("Crop Age") + ylab("SOC (%)") + ggtitle("") +
expand_limits(y=c(NA, 4.5))

The two equations that I want to plot are: y=0.08x + 1.54 and y=0.03x +
2.79.

Any help is appreciated.

Look at geom_abline with arguments for intercept and slope:
