Adding two regression graphs having problem in dots and lines
1
I cannot find my answer anywhere.
I have two regression lines from two different datasets. I am trying to put these two regression lines in one graph. The following worked well.
regression1<-lm(Y ~ X, data = mydata1)
regression2<-lm(Y ~ X, data = mydata2)
abline(regression1)
abline(regression2)
However in this plot I just have lines and I don't have dots. I run:
regression1<-lm(Y ~ X, data = mydata1)
regression2<-lm(Y ~ X, data = mydata2)
plot(c(0,2),c(0,2),type="n") +
points(rnorm(200), rnorm(200), col = "red")
abline(regression1)
abline(regression2)
With this command, I had just dots and I don't have lines, still does not work for me. What I want is having one graph with two different lines (representing the each regression's fitted lines) and dots of these regressions. I want these with different colours. Any help would be appreciated. Thanks

Can you post sample data? Please edit the question with the output ofdput(mydata1). Or, if it is too big with the output ofdput(head(mydata1, 20)). And the same withmydata2.

With me the problem, with a fake dataset, was to open the graphics device withplot(c(0,2), c(0,2), etc). The regression lines were outside the plotting area. I solved this problem withwith(mydata1, plot(range(X), range(Y), type = "n")).

When, using base R graphics, you plot something and it doesn't show up in the graph the odds are that you have plotted it outside the plot area. In the example below I will make sure that everything is in the plot area by first getting appropriate x and y axis limits.
The first two code lines do the trick.
rangeX <- range(c(mydata1$X, mydata2$X))
rangeY <- range(c(mydata1$Y, mydata2$Y))
regression1 <- lm(Y ~ X, data = mydata1)
regression2 <- lm(Y ~ X, data = mydata2)
plot(rangeX, rangeY, type = "n", xlab = "X", ylab = "Y")
with(mydata1, points(X, Y, col = "red"))
with(mydata2, points(X, Y, col = "blue"))
abline(regression1, col = "red")
abline(regression2, col = "blue")
Data creation code.
set.seed(1234)
n <- 20
x <- seq_len(n) + rnorm(n)
mydata1 <- data.frame(X = x, Y = x + rnorm(n))
x <- seq_len(n) + rnorm(n)
mu <- 3
mydata2 <- data.frame(X = x + rnorm(n), Y = mu + x + rnorm(n))

Can you post sample data? Please edit the question with the output of
dput(mydata1). Or, if it is too big with the output ofdput(head(mydata1, 20)). And the same withmydata2.– Rui Barradas

I am sorry I cannot share the data, could you give an example from datasets from the R?

With me the problem, with a fake dataset, was to open the graphics device with
plot(c(0,2), c(0,2), etc). The regression lines were outside the plotting area. I solved this problem withwith(mydata1, plot(range(X), range(Y), type = "n")).– Rui Barradas

reg1<-lm(Y ~ X, data = mydata1) reg2<-lm(Y ~ X, data = mydata2) with(mydata1, plot(range(X), range(Y), type = "n"))+ with(mydata2, plot(range(X, range(Y), type = "n")) + abline(reg1) abline(reg2)This does not work @RuiBarradas– ASD
