Join positive and negative numbers with different direction in one plot in R [closed]
I have posite and negative numbers, but in different direction. There is undesirable step change. How to put correctly values. Numbers -1 and 1 must be on the same level. Negative numbers on top half and vice versa.
Example:
x <- 1:10
y <- c(0.9, 0.92, 0.94, 0.96, 0.98, 1, -0.98, -0.96, -0.94,-0.92)
plot(x, y, type="b", ylab = "Value", xlab = "Time [seconds]")
plot with undesirable step change
r ggplot2 plot

Something like this ?plot(x, abs(y), type = "b", ylim = c(0, 1))

No. Ok maybe more accurate question: How to reverse only top half y axis in plot?

I've created a new vector new_y by adding 2 if y is negative and keeping y otherwise. But now the y axis ranges from 0 to 1,1 approximately
new_y <- ifelse(y<0,y+2,y)
plot(x, new_y, type="b", ylab = "Value", xlab = "Time [seconds]")

No, it doesnt work.. It is not so simply, because "ylim" does not change direction of positive or negative numbers...

I think I did not understand your question then, what do you mean by "change direction" ?

Make reverse only part y axis an then is -1 and 1 are on the same level without stepchange.
