Description Usage Arguments Details Value Examples

Expressions can be written in a natural way such as
`count_vals_inrows_byname(m, "<=", 1)`

.

1 2 3 4 5 | ```
count_vals_inrows_byname(
a,
compare_fun = c("==", "!=", "<", "<=", ">=", ">"),
val = 0
)
``` |

`a` |
a matrix or list of matrices whose values are to be counted by rows according to |

`compare_fun` |
the comparison function, one of " |

`val` |
the value against which matrix entries are compared. Default is |

Either a single matrix or a list of matrices can be given as the `a`

argument.
`compare_fun`

can be specified as a string (`"!="`

)
or as a back-quoted function (``!=``

).

an `matrix`

with a single column indicating the number of entries in `a`

that meet the specified criterion in each row of `a`

1 2 3 4 5 6 7 8 | ```
m <- matrix(c(0, 1, 2, 3, 4, 0), nrow = 3, ncol = 2)
count_vals_inrows_byname(m) # uses defaults: compare_fun = "==" and val = 0
count_vals_inrows_byname(m, compare_fun = "!=")
count_vals_inrows_byname(m, compare_fun = `!=`)
# Write expressions in a natural way
count_vals_inrows_byname(m, "<=", 1)
# Also works for lists
count_vals_inrows_byname(list(m,m), "<=", 1)
