Using mutate and a lookup/calc funtion - r

Question

I wrote a function where I pass a company name to lookup in a 2nd table a set of records, calculate a complicated result, and return the result.
I want to process all companies and add a value to each record with that result.
I am using the following code:
`aa <- mutate(companies,newcol=sum_rounds(companies$company_name))`
But I get the following warning:
Warning message:
In c("Bwom", "Symple", "TravelTriangle", "Ark Biosciences", "Artizan Biosciences", :
longer object length is not a multiple of shorter object length
(each of these is a company name)
The company dataframe gets a new column, but all values are "false" where actually there should be both true and false.
Any advice would be welcome to a newbie.
Function follows:
sum_rounds<-function(co_name) {
#get records from rounds for the company name passed to the function
#remove NAs from column roundtype too
outval<- rounds %>%
filter(company_name.x==co_name & !is.na(roundtype)) %>%
#sort by date round is announced
arrange(announced_on) %>%
select(roundtype) %>%
#create a string of all round types in order
apply(2,paste,collapse="")
#the values from mixed to "M", venture to "V" and pureangel to "A"
# now see if it is of the form aaaaa (and #) followed by m or v
# in grep: ^ is start of a line and + is for ar least one copy
# [mv] is either m or v
# nice summary is here: http://www.endmemo.com/program/R/gsub.php
#is angel2vc?
angel2vc<-grepl("^a+[mv]+",outval)
#return(list("roundcodes"=outval,"angel2vc"=angel2vc))
return(angel2vc)
}
