Update: Session info at the bottom
I want to mutate a column with "m-³" in a dataframe. Both the minus sign and 3 should be superscript:
The dataframe:
df <- tribble(
~x,
"m³",
"m³",
"m³",
"m³"
)
- I can get m³ by the keyboard -> column
x - I can get m³ by unicode
"\U006D\U00B3"
But a minus (unicode = "\U207B") is not possible.
I have tried so far:
df %>%
mutate(x1 = "\U006D\U00B3") %>% # unicode
mutate(x2 = "\U006D\U207B\U00B3")
# Output:
x x1 x2
<chr> <chr> <chr>
1 m³ m³ m<U+207B>³
2 m³ m³ m<U+207B>³
3 m³ m³ m<U+207B>³
4 m³ m³ m<U+207B>³
I am aware of expression and parse function but had no success.
