ble summary can val max sum overflow treat reat

Treat it as a data.frame:

set.seed(1)
x <- sample(30, 100, TRUE)

summary(x)
# Min. 1st Qu. Median Mean 3rd Qu. Max.
# 1.00 10.00 15.00 16.03 23.25 30.00
summary(data.frame(x))
# x
# Min. : 1.00
# 1st Qu.:10.00
# Median :15.00
# Mean :16.03
# 3rd Qu.:23.25
# Max. :30.00

For slightly more usable output, you can use data.frame(unclass(.)):

val = data.frame(unclass(summary(x)))
val
# val
# Min. 1.00
# 1st Qu. 10.00
# Median 15.00
# Mean 16.03
# 3rd Qu. 23.25
# Max. 30.00

val[1,1]
val[2,1]
val[3,1]

Or you can use stack:

stack(summary(x))
# values ind
# 1 1.00 Min.
# 2 10.00 1st Qu.
# 3 15.00 Median
# 4 16.03 Mean
# 5 23.25 3rd Qu.
# 6 30.00 Max.
