Specify the base of the log with base argument.

log_byname(a, base = exp(1))

Arguments

a

a matrix or list of matrices

base

the base of the logarithm (default is exp(1), giving the natural logarithm)

Value

M with each element replaced by its base base logarithm

Examples

log_byname(exp(1))
#> [1] 1
m <- matrix(c(10,1,1,100), nrow = 2, dimnames = list(paste0("i", 1:2), paste0("c", 1:2))) %>% setrowtype("Industry") %>% setcoltype("Commodity") log_byname(m)
#> c1 c2 #> i1 2.302585 0.00000 #> i2 0.000000 4.60517 #> attr(,"rowtype") #> [1] "Industry" #> attr(,"coltype") #> [1] "Commodity"
log_byname(m, base = 10)
#> c1 c2 #> i1 1 0 #> i2 0 2 #> attr(,"rowtype") #> [1] "Industry" #> attr(,"coltype") #> [1] "Commodity"
