readfile

问题 I'm trying to import a csv file in R. I have done it several times but with this specific file it returns me a error. On the first row of the csv I have the names of the colums that are in part text and in part numbers, as they represent month, year, and the numbers of some observational points. The .csv file, even if larger, looks as follows: Mo,Yr2,4,10,32,38,41,60,63,82 9,1980, 6.0, 0.2, 0.7, 1.0, 0.4, 0.7, 0.4, 1.5 10,1980, 25.1, 39.7, 41.4, 15.5, 20.8, 43.6, 37.1, 17.8 11,1980, 11.5, 8.6

问题 I have a UTF-8 encoded file "myFile.aaa" with non-printable char represented by hexadecimal x80 (decimal 128). I need to develop a Javascript function that will read this char from myFile.aaa and return its decimal value, 128. Is it possible to do that? How? If I copy myFile.aaa content to " var data ", and do " data[0].charCodeAt(0) " I get value 8364 instead of 128. Thanks 回答1: I don't think your UTF-8 encoding makes sense, so I'm going to tell you the best way I've found of dealing with

You could redirect

But that's the point, if you could identify who requested to read, you could block it for some processes. Using Fuse's C api, you
