ExtendHIT does't accept vector of HIT ids

[jyp256]

Hi. I am using "ExtendHIT" function. I tried to use a vector of HIT ids but keep getting an error message. I tried transforming the vector in various ways like "as.character()", etc. Still no luck.
When I feed in only one HIT ID, it works. However, a vector of HITs like the one below doesn't work.

So, I am just looping over each HIT id in a vector. However, I would like to just put a vector in the code as suggested in the package manual. Could you please help me with some solution? Thanks!

ExtendHIT(hit = as.character(c("371QPA24C1NJQUPVEKWBBRSWE3H1TJ", "3FCO4VKOZ3CVCXM0D5OPDFJ8EFU7EW")), add.seconds = seconds(days=7))
