# S3 method for numeric
nobs(object, ...)
# S3 method for integer
nobs(object, ...)
# S3 method for matrix
nobs(object, ...)
# S3 method for data.frame
nobs(object, ...)
# S3 method for character
nobs(object, ...)
# S3 method for factor
nobs(object, ...)

Examples

suppressWarnings(RNGversion("3.5.0"))
set.seed(1)
## numeric vector
len <- sample(1:10, 1)
v <- as.numeric(sample(1:100, len))
len
obs <- nobs(v)
isTRUE(all.equal(len, obs))

## integer
len <- sample(1L:10L, 1)
obs <- nobs(len)
isTRUE(all.equal(len, obs))
