Concatenate a vector of strings/character
Try using an empty collapse argument within the paste function:
paste(sdata, collapse = '')
You can use stri_paste function with collapse parameter from stringi package like this:
stri_paste(letters, collapse='')## [1] "abcdefghijklmnopqrstuvwxyz" And some benchmarks:
require(microbenchmark)test <- stri_rand_lipsum(100)microbenchmark(stri_paste(test, collapse=''), paste(test,collapse=''), do.call(paste, c(as.list(test), sep="")))Unit: microseconds expr min lq mean median uq max neval stri_paste(test, collapse = "") 137.477 139.6040 155.8157 148.5810 163.5375 226.171 100 paste(test, collapse = "") 404.139 406.4100 446.0270 432.3250 442.9825 723.793 100do.call(paste, c(as.list(test), sep = "")) 216.937 226.0265 251.6779 237.3945 264.8935 405.989 100
