diffAdats: Diff Two ADAT Objects

In SomaDataIO: Input/Output 'SomaScan' Data

Diff Two ADAT Objects

Description

Diff tool for the differences between two soma_adat objects. When diffs of the table values are interrogated, only the intersect of the column meta data or feature data is considered

Usage

diffAdats(adat1, adat2, tolerance = 1e-06)

Arguments

adat1, adat2	Two soma_adat objects to compare.
tolerance	Numeric ⁠> 0⁠. Differences smaller than tolerance are not triggered. See all.equal().

Value

NULL, invisibly. Called for side effects.

Note

Only diffs of the column name intersect are reported.

Examples

# subset `example_data` for speed
# all SeqIds from 2000 -> 2999
seqs <- grep("^seq\\.2[0-9]{3}", names(example_data), value = TRUE)
ex_data_small <- head(example_data[, c(getMeta(example_data), seqs)], 10L)
dim(ex_data_small)

# no diff to itself
diffAdats(ex_data_small, ex_data_small)

# remove random column
rm <- withr::with_seed(123, sample(1:ncol(ex_data_small), 1))
diffAdats(ex_data_small, ex_data_small[, -rm])

# randomly shuffle Subarray
diffAdats(ex_data_small, dplyr::mutate(ex_data_small, Subarray = sample(Subarray)))

# modify 2 RFUs randomly
new <- ex_data_small
new[5L, c(rm, rm + 1L)] <- 999
diffAdats(ex_data_small, new)
