Arguments
- x
vector
- method
how to melt, should be one of
first|last, or one of sum|mean|median for numeric vector,
or some characters (e.g. ,|.| |;) for character vector
- invalid
invalid value to ignore, NA as default
Value
melted single value
Examples
melt_vector(c(NA, 2, 3), method = "first")
#> [1] 2
melt_vector(c(NA, 2, 3), method = "sum")
#> [1] 5
melt_vector(c(NA, 2, 3), method = ",")
#> [1] "2,3"
melt_vector(c(NA, 2, Inf), invalid = c(NA, Inf))
#> [1] 2
