Trouble with reading CSV file in R -


I'm a newbie in R. I have a 24 MB CSV file. It reads in RStudio on my MacBook Air with OS Yoswmite, 4 GB RAM. R Version 3.1.1 (2014-07-10). See the content (DF) is okay. Trying to apply filter No hits get the character from the number trying to the number Transfer all the shepherds to the column with NA where the castings are done! What happened here? It seems that the contents of R cells can not read anything about encoding? First of all, a summary: this is what I have to rent so much.

R Code:

  eiendommer & lt; - read.csv ("eiendommer.csv" September = ",", quote = "", encoding = "UTF-8", stringsAsFactors = false) (eiendommer) # I can view the csv file filtereiendommer & lt content; - Filters (eiendommer, kommune == "0101") # no counterattack filtereiendom & lt; - eiendommer [eiendommer $ kommune == "0101",] # no contest utvalg & lt; - eiendommer [160,567: 161,934,] # manual selection of rows utvalgsortert & lt work; - Arrangement (utvalg, desc (jordbruksareal), dis (schogieral) # see the work (Utvolgusstst) ## Try changing the column from number to character. TransformedEiendom & lt; The results in #This NA were the characters with 1-3 of lengt: "646", "18", "64", "transformer", "transform" 2 ".  

X.festenr Bruksnavn jordbruksareal Length: 207,554 Length: 207,554 Length: 207,554 Length: 207,554 Length: 207,554 Length: 207,554 Category: Character Class: Character Class: Character Class: Character Moderate: Character Mod: Character Mode: Character mode: Character mode: Character mode: Character X.annetareal Schogeral X.

It will appear that you have specified quote =" " where you really should be, and maybe quote = '' '' or just The default value will work

See the examples given below

  D & lt; - data.frame (x = 'a', y = '' a '', strings effectors = FALSE) D # xy # 1 a "a"  

For a regular character vector, print.data.frame it will not be used in "
