It is possible to create a string vector as output when merging factors, by using the as.character()
function. Here's an example:
# create two factors
x <- factor(c("red", "green", "blue"))
y <- factor(c("small", "medium", "large"))
# merge the factors and convert to a string vector
z <- as.character(merge(x, y))
# print the result
print(z)
[1] "blue.large" "green.medium" "red.small"
In this example, we merge the factors x
and y
using the merge()
function, which combines each level of one factor with each level of the other factor. The resulting factor is then converted to a character vector using as.character()
. The resulting vector z
contains strings with the form "level1.level2"
.
