Answer 1

You could also do:

  library(stringr)
   txt2 <- str_extract_all(text, "[^,]+")[[1]]
   paste(paste(txt2[-length(txt2)],txt2[-1],sep=" "), collapse=", ")
   #[1] "Lorem ipsum, ipsum dolor, dolor sit, sit amet, amet consectetuer"

Or

  library(gsubfn)
   paste(strapply(text, "([^,]+),(?=([^,]+))", paste, backref= -2, perl=TRUE)[[1]], collapse=",")
   #[1] "Lorem ipsum,ipsum dolor,dolor sit,sit amet,amet consectetuer"
