Utilities Useful tools for programming.

Usage

now()

bquote.arg(x)

check.types(...)

quantize(x, init, step, bias = c("round", "floor", "ceiling"))

Arguments

x	a vector of values
...	named arguments, where the name of the argument is a variable class, and the argument itself is the value to be checked for its type. function cannot be provided as argument name, so the shorthand fun must be used.
init	an initial value
step	steps over which to be quantized
bias	when quantizing, should the value be rounded up or down?

Details

now() returns the current numeric Linux timestamp.

bquote.arg() is to be used inside functions. It returns the content of the argument as a call, but evaluates parts of the argument that were wrapped inside .(), akin to bquote().

check.types() checks the class of its arguments, and errors if an argument does not match the class that was provided as argument name.

quantize() quantizes a vector.

Value

quantize() returns a quantized numeric vector.

Examples

now()
testfunction<-function(x){ bquote.arg(x) }
testfunction(a + b)
# a + b
testfunction(a + b + .(5+5))
# a + b + 10
check.types(numeric=3,character="a",fun=read.csv)
# TRUE
## Not run: 
check.types(numeric="3")

## End(Not run)
# Error in check.types(numeric = "3") :
# Argument 1 with value 3 should be of type numeric, but is of type character
quantize(1:20,0.5,2,"ceiling")
# 2.5  2.5  4.5  4.5  6.5  6.5  8.5  8.5 10.5 10.5 12.5 12.5 14.5 14.5 16.5 16.5 18.5 18.5 20.5 20.5
