Plot_ly doesn't plot anything

Hello,

The following code does not produce a plot (even plots > save as Image in RStudio doesn’t work):

library(plotly)

library(ggplot2)
norme2 = function(x){

return(sqrt(sum(x^2)))

}

simuNormale = function(n) {

u = runif(n)
v = runif(n)
x = sqrt(-2log(u))sin(2piv)

return(x)

}

simuSphere = function(d, n){

X = matrix(nrow = n, ncol = d)

for(i in 1:n){

N = simuNormale(d)

X[i,] = N/norme2(N)

}

return(X)
}

Y = simuSphere(3, 10000)
Y = as.data.frame(Y)
names(Y) <- c(“x”, “y”, “z”)
plot_ly(data = Y, x = ~x, y = ~y, z = ~z, type = “scatter3d”, mode = “markers”)
