title: R - csv write / read changes decimal separator
body: <p>in R, when using </p>
  
  <p><code>write.csv(df, file = "/path/dataframeX.csv",row.names=FALSE, fileEncoding = "UTF-8")</code> </p>
  
  <p>and then reading the csv with </p>
  
  <p><code>read.csv("/path/dataframeX.csv", header = T, na.strings=c(""," ","NA"))</code></p>
  
  <p>it changes my point separated values to comma separated values (e.g. 4.32 becomes 4,32). Is there a way to avoid this? What mistake am I doing?</p>
  
  <p>edit: solved - add <code>dec = ","</code> to the <code>read.csv()</code></p>
  
  <p>Thank you very much and best regards,</p>
  
  <p>Jimmy</p>
