I want to import an XML file from polarpersonaltrainer.com that stores heartrate data into a R data.frame. Is there a package that makes importing XML easy or do I have to write my own parser?

An XML file can be read in R using the function xmlParse() . Then, load data is stored in a list. An XML file can also be read in the form of a data frame by using the xmlToDataFrame() method.
File formats like csv, xml, xlsx, json, and web data can be imported into the R environment to read the data and perform data analysis, data manipulations and after data analysis data in R can be exported to external files in the same file formats.
Reading a simple XML file in R You can read an XML file in R using the “xml2” package. xml2:library turns an XML document into the equivalent R list. read_xml() function from the library xml2 reads XML file specified as a path which can be a local file path or a URL.
It stands for Extensible Markup Language (XML). Similar to HTML it contains markup tags. But unlike HTML where the markup tag describes structure of the page, in xml the markup tags describe the meaning of the data contained into he file. You can read a xml file in R using the "XML" package.
Yes. Use the XML package. There's a function called xmlToDataFrame which will make your life easy.
