paste text with a newline/return in formatted text

I want to do a column that is formatted to use for a mailing address and I can not get the newline/return carriage or
to work when making a new column.

name = c("John Smith", "Patty Smith", "Sam Smith")
address = c("111 Main St.", "222 Main St.", "555 C Street")
cityState = c("Portland, OR 97212", "Portland, OR 95212", "Portland, OR 99212")
df <- data.frame(name, address, cityState)

I want to create a column that formats the data in an address label:
John Smith
111 Main st.
Portland, OR 97212

Each new column: will have a return after each line: so it is always 3 lines. One line for each of the other 3 columns.

# example of what I am trying to do...
paste0(name, "return", address, "return", cityState). Everything I have tried does not work for making a newline.


You need to paste it together with a newline (\n) separator. To assemble it from df,

addresses <- apply(df, 1, paste, collapse = '\n')

If you print it normally, it will show you the \n characters:

## [1] "John Smith\n111 Main St.\nPortland, OR 97212" 
## [2] "Patty Smith\n222 Main St.\nPortland, OR 95212"
## [3] "Sam Smith\n555 C Street\nPortland, OR 99212"  

To print with the newlines evaluated use cat, also with sep = '\n' to insert line breaks between items:

cat(addresses, sep = '\n')
## John Smith
## 111 Main St.
## Portland, OR 97212
## Patty Smith
## 222 Main St.
## Portland, OR 95212
## Sam Smith
## 555 C Street
## Portland, OR 99212
