is_intact_attr {SomaDataIO}

Are Attributes Intact?

Description

This function runs a series of checks to determine if a soma_adat object has a complete set of attributes. If not, this indicates that the object has been modified since the initial read_adat() call. Checks for the presence of both "Header.Meta" and "Col.Meta" in the attribute names. These entries are added during the read_adat() call. Specifically, within these sections it also checks for the presence of the following entries:

"Header.Meta" section:

"HEADER", "COL_DATA", and "ROW_DATA"

"Col.Meta" section:

"SeqId", "Target", "Units", and "Dilution"

If any of the above they are altered or missing, FALSE is returned.

is.intact.attributes() is . It remains for backward compatibility and may be removed in the future. You are encouraged to shift your code to is_intact_attr().

Usage

is_intact_attr(adat, verbose = interactive())

is.intact.attributes(adat, verbose = interactive())

Arguments

adat

A soma_adat object to query.

verbose

Logical. Should diagnostic information about failures be printed to the console? If the default, see interactive(), is invoked, only messages via direct calls are triggered. This prohibits messages generated deep in the call stack from bubbling up to the user.

Value

Logical. TRUE if all checks pass, otherwise FALSE.

# checking attributes
my_adat <- example_data
is_intact_attr(my_adat)           # TRUE
is_intact_attr(my_adat[, -303L])   # doesn't break atts; TRUE
attributes(my_adat)$Col.Meta$Target <- NULL    # break attributes
is_intact_attr(my_adat)  # FALSE (Target missing)
