Install the R package.

    install.packages("udpipe")

## Example

Get your language model and start annotating.

    library(udpipe)
    udmodel <- udpipe_download_model(language = "dutch")

    udmodel <- udpipe_load_model(file = udmodel$file_model)
    x <- udpipe_annotate(udmodel,
                         x = "Ik ging op reis en ik nam mee: mijn laptop, mijn zonnebril en goed humeur.")
    x <- as.data.frame(x, detailed = TRUE)

Or just do as follows.

    library(udpipe)
    x <- udpipe(x = "Ik ging op reis en ik nam mee: mijn laptop, mijn zonnebril en goed humeur.",
                object = "dutch")

The annotation returns paragraphs, sentences, tokens, the location of the token in the original text, morphology elements like the lemma, the universal part of speech tag and the treebank-specific parts of speech tag, morphosyntactic features and returns as well the dependency relationship.

## A small note on encodings

Mark that it is important that the `x` argument to `udpipe_annotate` is in UTF-8 encoding. You can check the encoding of your text with `Encoding('your text')`. You can convert your text to UTF-8, using standard R utilities: as in `iconv('your text', from = 'latin1', to = 'UTF-8')` where you replace the `from` part with whichever encoding you have your text in, possible your computers default as defined in `localeToCharset()`. So annotation would look something like this if your text is not already in UTF-8 encoding:

- `udpipe_annotate(udmodel, x = iconv('your text', to = 'UTF-8'))` if your text is in the encoding of the current locale of your computer.
- `udpipe_annotate(udmodel, x = iconv('your text', from = 'latin1', to = 'UTF-8'))` if your text is in latin1 encoding.
- `udpipe_annotate(udmodel, x = iconv('your text', from = 'CP949', to = 'UTF-8'))` if your text is in CP949 encoding.
