Try something like this where we use the built in data frame anscombe:

opar <- par(mfrow = c(1, 2), no.readonly = TRUE)
matplot(1:11, anscombe[1:4], pch = 1:4, col = 1:4, log = "x", ylab = "Y")
matplot(1:11, anscombe[5:8], pch = 1:4, col = 1:4, log = "x", ylab = "Y")
par(opar)
I am new to R and have a problem that I haven't been able to find the answer to in the guides or online.

I have multiple datasets, D1, D2, D3, D4, D5, D6, D7 and D8, and I would like to produce two plots side by side using mfrow.  The first plot should contain data from D1-D4, the second should contain D5-D8.

I can plot these separately using the code,

par(mfrow=c(1,1))
plot(c(0.000001,1),c(0,100),type="n", xlab="D", ylab="% R", log="x")
     points(D1$L0,D1$K1_R1,lwd=2, col="blue", )
     points(D2$L0,D2$K1_R2,lwd=2, col="red", )
     points(D3$L0,D3$K1_Rt3,lwd=2, col="orange", )
     points(D4$L0,D4$K1_R4,lwd=2, col="black", )

or

par(mfrow=c(1,1))
plot(c(0.000001,1),c(0,100),type="n", xlab="D", ylab="% R", log="x")
     points(D5$L0,D1$K2_R1,lwd=2, col="blue", )
     points(D6$L0,D2$K2_R2,lwd=2, col="red", )
     points(D7$L0,D3$K2_Rt3,lwd=2, col="orange", )
     points(D8$L0,D4$K2_R4,lwd=2, col="black", )

but how can I plot them together?

Thanks in advance for your help, I appreciate any help you can give.

If I understand you correctly, you need to specify mfrow argument as c(1,2) and then make your two calls to plot().  HTH ...

Subject: [R] How to plot multiple graphs each with multiple y 
variables

I am new to R and have a problem that I haven't been able to 
find the answer to in the guides or online.

I have multiple datasets, D1, D2, D3, D4, D5, D6, D7 and D8, 
and I would like to produce two plots side by side using 
mfrow.? The first plot should contain data from D1-D4, the 
second should contain D5-D8.

I can plot these separately using the code,

par(mfrow=c(1,1))
plot(c(0.000001,1),c(0,100),type="n", xlab="D", ylab="% R", log="x")
???? points(D1$L0,D1$K1_R1,lwd=2, col="blue", )
???? points(D2$L0,D2$K1_R2,lwd=2, col="red", )
???? points(D3$L0,D3$K1_Rt3,lwd=2, col="orange", )
???? points(D4$L0,D4$K1_R4,lwd=2, col="black", )

or

par(mfrow=c(1,1))
plot(c(0.000001,1),c(0,100),type="n", xlab="D", ylab="% R", log="x")
???? points(D5$L0,D1$K2_R1,lwd=2, col="blue", )
???? points(D6$L0,D2$K2_R2,lwd=2, col="red", )
???? points(D7$L0,D3$K2_Rt3,lwd=2, col="orange", )
???? points(D8$L0,D4$K2_R4,lwd=2, col="black", )

but how can I plot them together?

Thanks in advance for your help, I appreciate any help you can give.
