R: Subscript Out of Bounds, Execution Halted

I am working with the R programming language. I am trying to follow the instructions over here: https://stat.ethz.ch/R-manual/R-devel/library/MASS/html/parcoord.html

 library(MASS)
   a = rnorm(100,10,10)
    b = rnorm(100,10,5)
    c = rnorm(100,5,10)
    d = as.matrix(a,b,c)
    
     parcoord(d[, c(3, 4, 2)], col = 1 + (0:149)%/%50)

It produces the following error:

    Error in d[, c(3, 4, 2)] : subscript out of bounds
    Calls: parcoord -> apply
    Execution halted

Does anyone know how to fix this error? Is it also possible to label the axis and put a title on the plot?

Thanks

Your subscript is out of bounds

The subscript is [ ,c(3,4,2)]

Out of bounds means that you're indexing columns that don't exist. This is because d is a column vector - a matrix with only one column. This is happening because you're using as.matrix incorrectly.

You could make a three column matrix with: d <- matrix(c(a, b, c), ncol = 3), but even then your subscript won't work, because your subscript is looking for column four.
