justification | R Documentation |
The justification
function extracts all assigned justify
attributes from a
data frame, and returns them in a named list. The function also
assigns justify attributes from a named list.
justification(x)
justification(x) <- value
x |
A data frame or tibble |
value |
A named list of justification values. |
If justification values are assigned to the "justify"
attributes of the data frame
columns, the justification
function will extract those values. The
function will return the justification values in a named list,
where the names
correspond to the name of the column that the justification was assigned to.
If a column does not have a justify attribute assigned, that column
will not be included in the list.
When used on the receiving side of an assignment, the function will assign justification to a data frame. The justification values should be in a named list, where each name corresponds to the name of the data frame column to assign values to.
Finally, if you wish to clear out the justification attributes, assign
a NULL value to the justification
function.
A named list of justification values.
fdata
to display formatted data,
value
to create user-defined formats, and
fapply
to apply formatting to a vector.
# Take subset of data
df1 <- mtcars[1:10, c("mpg", "cyl") ]
# Print current state
print(df1)
# Assign justification
justification(df1) <- list(mpg = "left", cyl = "right")
widths(df1) <- list(mpg = 12, cyl = 10)
fdata(df1)
# Display justification
justification(df1)
widths(df1)
# Clear justification
justification(df1) <- NULL
# Confirm justifications are cleared
justification(df1)
