Dear All,
Let 499 piece-wise lines were buit up by 500 pair of observations, via R code
below.
x - 1:500
y - rnorm(500)
plot(x, y, type = 'b')
I was trying to compute all the slopes for the lines which were connected
between two adjacent points. For instance, slopes of lines between first
Hi,
Like this perhaps?
slope = diff(y) / diff(x)
str(slope)
num [1:499] 1.5068 -1.8406 2.1745 0.0676 -2.6088 ...
