Rule:

• Principle: Function arguments that consist of a braced expression always need to start on a new line

• Exception: ... unless it's the last argument and all other arguments fit on the line of the function call

• Exception: ... or they are named.

• Extension: Also, expressions following on braced expressions also cause a line trigger.

## Examples

if (FALSE) {
tryCatch(
{
f(8)
},
error = function(e) NULL
)
# last-argument case
testthat("braces braces are cool", {
code(to = execute)
})
call2(
x = 2,
{
code(to = execute)
},
c = { # this is the named case
g(x = 7)
}
)
tryGugus(
{
g5(k = na)
},
a + b # line break also here because
# preceded by brace expression
)

# brace expressions go on new line if part of a pipe, in function call...
c(
data %>%
filter(bar) %>%
{
cor(.$col1, .$col2, use = "complete.obs")
}
)
# ... or outside
data %>%
filter(bar) %>%
{
cor(.$col1, .$col2, use = "complete.obs")
}
}
