matchds_1to2: Match two datasets on rows and columns

In metamaden/recountmethylation: Access and analyze public DNA methylation array data compilations

Match two datasets on rows and columns

Description

Match 2 datasets using the character vectors of row or column names. This is used to assemble an "RGChannelSet" from a query to an h5 dataset.

Usage

matchds_1to2(
  ds1,
  ds2,
  mi1 = c("rows", "columns"),
  mi2 = c("rows", "columns"),
  subset.match = FALSE
)

Arguments

ds1	First dataset to match
ds2	Second dataset to match
mi1	Match index of ds1 (either "rows" or "columns")
mi2	Match index of ds2 (either "rows" or "columns")
subset.match	If index lengths don't match, match on the common subset instead

Value

A list of the matched datasets.

Examples

# get 2 data matrices
ds1 <- matrix(seq(1, 10, 1), nrow = 5)
ds2 <- matrix(seq(11, 20, 1), nrow = 5)
rownames(ds1) <- rownames(ds2) <- paste0("row", seq(1, 5, 1))
colnames(ds1) <- colnames(ds2) <- paste0("col", c(1, 2))
ds2 <- ds2[rev(seq(1, 5, 1)), c(2, 1)]
# match row and column names
lmatched <- matchds_1to2(ds1, ds2, mi1 = "rows", mi2 = "rows")
lmatched <- matchds_1to2(lmatched[[1]], lmatched[[2]], mi1 = "columns", 
 mi2 <- "columns")
# check matches
ds1m <- lmatched[[1]]
ds2m <- lmatched[[2]]
identical(rownames(ds1m), rownames(ds2m))
identical(colnames(ds1m), colnames(ds2m))
