Reading a csv file with embedded quotes into R

问题 I have to work with a .csv file that comes like this: "IDEA ID,""IDEA TITLE"",""VOTE VALUE""" "56144,""Net Present Value PLUS (NPV+)"",1" "56144,""Net Present Value PLUS (NPV+)"",1" If I use read.csv, I obtain a data frame with one variable. What I need is a data frame with three columns, where columns are separated by commas. How can I handle the quotes at the beginning of the line and the end of the line? 回答1: I don't think there's going to be an easy way to do this without stripping the

CSV parsing with Commons CSV - Quotes within quotes causing IOException

由 [亡魂溺海] 提交于 2019-12-01 06:16:28
I am using Commons CSV to parse CSV content relating to TV shows. One of the shows has a show name which includes double quotes; 116,6,2,29 Sep 10,""JJ" (60 min)"," http://www.tvmaze.com/episodes/4855/criminal-minds-6x02-jj " The showname is "JJ" (60 min) which is already in double quotes. This is throwing an IOException java.io.IOException: (line 1) invalid char between encapsulated token and delimiter. ArrayList<String> allElements = new ArrayList<String>(); CSVFormat csvFormat = CSVFormat.DEFAULT; CSVParser csvFileParser = new CSVParser(new StringReader(line), csvFormat); List<CSVRecord>

PHP array_map trim + parameters

由 馋奶兔 提交于 2019-12-01 06:12:11
I'm using array_map to trim all my array values but I need to pass a third parameter because I need to more than just trim whitespaces so I'm passing in a third parameter. Basically I want to trim all array values of whitespaces, single quotes, and double quotes. I have a utility class where I created the function and it looks like this: public function convertToArray($string, $trim = false) { $split = explode(",", $string); if($trim) { $split = array_map("trim", $split, array(" '\"")); } return $split; } Somehow I can't make this work though. I can still see double quotes in the result even

Java String use quotes without escape character

由 不打扰是莪最后的温柔 提交于 2019-12-01 04:21:06
I know that it is possible to write double quotes in Java strings by putting \ symbol before them. But if double quotes are used a lot in a string, is there a way to mark the string once, so there won't be a need to write the \ symbol before each? (just like in C#, it is possible to put the @ symbol before the string) Example: String quotes = @""""""""""""""""""""; instead of String quotes = "\"\"\"\"\"\"\"\"\"\"\""; You can't. But if you are too lazy to escape each of the double quotes, there are some trick that can do that. For example: String quotes = "....................".replace(".","\""

perl encapsulate single variable in double quotes

In Perl, is there any reason to encapsulate a single variable in double quotes (no concatenation) ? I often find this in the source of the program I am working on (writen 10 years ago by people that don't work here anymore): my $sql_host = "something"; my $sql_user = "somethingelse"; # a few lines down my $db = sub_for_sql_conection("$sql_host", "$sql_user", "$sql_pass", "$sql_db"); As far as I know there is no reason to do this. When I work in an old script I usualy remove the quotes so my editor colors them as variables not as strings. I think they saw this somewhere and copied the style

write csv file with double quotes for particular column not working

由 邮差的信 提交于 2019-12-01 01:06:33
问题 I'm trying to write a csv file using python csv writer. In which one of the column value is enclosed in "" [double quotes] e.g. : 'col1' 'col2' "test", when I open the file in wordpad, the word test is expected as "test" but actual result is """test""" can someone guide for this issue. Sample snippet of my try out: csvReader = csv.reader(iInputFile) writer = csv.writer(open('one_1.csv', 'wb'), delimiter=',', lineterminator='\r\n') for row in csvReader: rawRow = [] rawRow.append('31-7-2014')

Adding quotes to argument in C++ preprocessor

由 蓝咒 提交于 2019-11-30 10:59:29
I'd like to pass the name of an include file as a compiler argument so that I can modify a large number of configuration parameters. However, my C++ build is via a makefile like process that removes quotes from arguments passed to the compiler and pre-processor. I was hoping to do something equivalent to #ifndef FILE_ARG // defaults #else #include "FILE_ARG" #endif with my command line including -DFILE_ARG=foo.h. This of course doesn't work since the preprocessor doesn't translate FILE_ARG. I've tried #define QUOTE(x) #x #include QUOTE(FILE_ARG) which doesn't work for the same reason. For
