Alternatively,
see rowQuantiles() in the matrixStats package.

Simple Question
I have 100x100 matrix and I want to calculte each row's 30,50% quantile
ex)
a=matrix(rnorm(1),100,100)
quantile(a[1,],c(0.3,0.5))
quantile(a[2,],c(0.3,0.5))
.
.
.
.
I want get results at once.
so I try quantile(a[1:100,],c(0.3,0.5)) but I can get what I exactly want.
Hi,

Basically you apply() the quantile function to each row (the 1, 2
would indicate columns) in the object 'a'.

Hi,
A simple quantile question:
I need to calculate the 95% and 5% quantiles (aka percentiles) for the
following data:
67.12
64.51
62.06
55.45
51.41
43.78
10.74
10.14
if I use the formula: 95% quantile point= 95 (8+1)/100, I get the 8.55th
point as the 95% quantile. Which does not make too much

Hi,
A simple quantile question:
I need to calculate the 95% and 5
have a look at the online help file of ?quantile(); check also:
x - c(67.12, 64.51, 62.06, 55.45, 51.41, 43.78, 10.74, 10.14)
sapply(1:9, function (i) quantile(x, c(0.05, 0.95), type = i))
I hope it helps.
Best,
Dimitris
