CheckData: Set of function to test conformity of data

Description

check_time: check if the time within a time serie is (1) numeric, (2) unique, (3) minimal value is 0.
check_concentration: check if the concentration is numeric and always positive.
check_Nsurv: check if the Nsurv is (1) integer and (2) always positive (3) can be NA.
check_TimeNsurv: check if the pair time - Nsurv within a time serie satisfies (1) Nsurv at t=0 is >0, (2) decreasing.
check_concNsurv: check if the pair conc - Nsurv within a time serie satisfies that the timeline of concentration covers timeline of Nsurv.
checking_table: add msg in a data.frame data if check are not all TRUE.
is_exposure_constant: Test in a well-formed argument to function SurvData if the concentration is constant and different from NA for each replicate (each time-serie).
is.between: Test if x is between min and max

Usage

check_time(data)
check_concentration(data)
check_Nsurv(data)
check_TimeNsurv(data)
check_concNsurv(data)
checking_table(data, check, msg)
is_exposure_constant(data)
is.between(x, min, max)

Value

a boolean TRUE if concentration in replicate is constant, or FALSE if the concentration in at least one of the replicates is time-variable, and/or if NA occurs.

Arguments

data: a data.frame
check: binary vector of TRUE/FALSE
msg: a message to add to the data.frame
x: parameter to check if it's between min and max
min: minimal value. x must be greater than min
max: maximal value. x must be lower than max
