Compare feature expression correlation across two data sets.
plotCountsCorrelation(x, y, ...)
# S4 method for matrix,matrix
plotCountsCorrelation(x, y, i = NULL,
j = NULL, xTitle = deparse(substitute(x)),
yTitle = deparse(substitute(y)), labs = list(colour = NULL, x = NULL,
y = NULL, title = NULL, subtitle = NULL))
Arguments
x 
Object. 
y 
Object. 
i 
indices specifying elements to extract or replace. Indices are
numeric or character vectors or empty (missing) or
NULL . Numeric values are coerced to integer as by
as.integer (and hence truncated towards zero).
Character vectors will be matched to the names of the
object (or for matrices/arrays, the dimnames ):
see ‘Character indices’ below for further details.
For [ indexing only: i , j , … can be
logical vectors, indicating elements/slices to select. Such vectors
are recycled if necessary to match the corresponding extent.
i , j , … can also be negative integers,
indicating elements/slices to leave out of the selection.
When indexing arrays by [ a single argument i can be a
matrix with as many columns as there are dimensions of x ; the
result is then a vector with elements corresponding to the sets of
indices in each row of i .
An index value of NULL is treated as if it were integer(0) . 
j 
indices specifying elements to extract or replace. Indices are
numeric or character vectors or empty (missing) or
NULL . Numeric values are coerced to integer as by
as.integer (and hence truncated towards zero).

xTitle 
character(1) .
Name of object defined in x .

yTitle 
character(1) .
Name of object defined in y .

labs 
list .
ggplot2 labels. See ggplot2::labs() for details.
