You can do this using the popular stringr and dplyr libraries. <\/p>\n

library(dplyr)\nlibrary(stringr)\n\ndf <- tibble(\n  sentence = c(\n    \"Time & tide waits for none\",\n    \" Tit for tat\",\n    \"Eyes are mirror of person's thoughts\",\n    \"Some Other Sentence\",\n    \"Odd sentences failure\"\n  )\n)\n\ndf <- df %>%\n  # Split the sentence and store it in a new column\n  mutate(split_sentence = str_split(sentence,\" \")) %>%\n  # Do the next step row wise because we will be dealing with a vector of vectors\n  rowwise() %>%\n  # Keep only words that have a remainder of 0 when divided by 2 (str_length modulo 2)\n  mutate(split_sentence = list(split_sentence[str_length(split_sentence) %% 2 == 0])) %>%\n  # Only keep non-null strings !\"\"\n  mutate(split_sentence = list(split_sentence[str_length(split_sentence) > 0])) %>%\n  # Find the first word with the longest length\n  mutate(split_sentence = list(split_sentence[which.max(str_length(split_sentence))])) %>%\n  # Keep only the first word left in the vector or return NA if none left\n  mutate(first_even = first(split_sentence)) %>%\n  # Ungroup because we don't need to work rowwise anymore\n  ungroup() %>%\n  # Convert any NA values to \"00\" per question\n  mutate(first_even = ifelse(is.na(first_even),\"00\",first_even)) %>%\n  select(-split_sentence)\n\n# A tibble: 5 x 2\n#   sentence                             first_even\n#   <chr>                                <chr>     \n# 1 Time & tide waits for none           Time      \n# 2 \" Tit for tat\"                       00        \n# 3 Eyes are mirror of person's thoughts person's  \n# 4 Some Other Sentence                  Sentence  \n# 5 Odd sentences failure                00       \n<\/code><\/pre>\n
In your description you said that thoughts<\/code> would be the longest word but my alogrithm found that person's<\/code> was just as long. If you want to remove the appostrophe you can figure out how to do that using the str_remove_all()<\/code> function. I’ll leave that for you.<\/p>\n<\/p><\/div>\n
