R: Incorrect encoding of narrow space in data frame and resulting .csv
I scraped data and received some character variables containing a narrow no break space (unicode U+202F). The resulting character variable shows up fine in R if it is in a vector. For example, the return of test shows up with a narrow space in the console:
test <- "variable1 variable2" <br> test
The offender is
test <- "variable1\u202Fvariable2" print(test)  "variable1 variable2" format(test) # "variable1<U+202F>variable2"
format gets called by
format.data.frame which in turn is called by
A solution might be to define a character method:
format.character <- function(x, ...) x DF <- data.frame(x = 1:5) #beware of stringsAsFactors DF$test <- test DF #spaces are actually thin spaces in R console # x test #1 1 variable1 variable2 #2 2 variable1 variable2 #3 3 variable1 variable2 #4 4 variable1 variable2 #5 5 variable1 variable2
Obviously, such a simple method will break functions relying on other
OTOH, why do you care how thin spaces are printed?

Work with data stored in different columns within a data.frame in R. Examine R object structures and data classes. Convert dates, stored as a character class, into an R date class. Create a quick plot of a time-series dataset using qplot.
One method is to convert all unicode characters to blank using
text <- "variable1\u202Fvariable2" new_text <- gsub("[^\x20-\x7E]", " ", text)
Here I match the negation of all commonly used ASCII characters, ranging from hex code 20 (SPACE) to 7E (~). The disadvantage of this method is that you might unintentionally remove more than what you wish, but you can always add exclusions to the character class.

Data Input, Reads a file in table format and creates a data frame from it, with cases fileEncoding = "", encoding = "unknown", text, skipNul = FALSE) read.csv(file, If sep = "" (the default for read.table ) the separator is 'white space', that is one or more Notice that a literal string can be used to include (small) data sets within R code. In order to export the data-frame into CSV we can use the below code. > write.csv(df, 'C:\\Users\\Pantar User\\Desktop\\Employee.csv', row.names = FALSE) In the above line of code, we have provided a path directory for our data fame and stored the dataframe in CSV format.

Chapter 24 String processing, A data scientist will rarely have such luck and will have to import data into R It is basically a file version of a data frame. The most common characters are comma ( , ), semicolon ( ; ), space ( ), and We will use the murders.csv file provided by the dslabs package as an example. Save the result to an object called dat . We have learned to write CSV file in R by using R base functions. The write.csv(), write.csv2() and write.table() can be used to write CSV file. Note that the write.table() function to write different types of text files in R. Here are other posts related to process data in R, you may refer to them if you’re interested in: R – How To Order

- What's wrong with using
gsub, or regex for that matter?
- It is error prone and a workaround rather than a solution.
- I do not care how they are printed but the observations in the resulting csv file should exactly be the scraped text, i.e.
"variable1 variable2", not
- Well, you are obviously in encoding hell. I don't know how to fix the file export.
- Would it be possible to post reproducible code including the scraping ?
