例如,可以使用write.csv(df, file = "data.csv", na = "")来将缺失值保存为空字符串。 6.引用字符:如果某个值包含分隔符或换行符,则该值会被引用起来保存,以确保文件的一致性。默认情况下,CSV文件的引用字符是双引号(")。可以通过设置参数quote = FALSE来禁止使用引用字符。例如,可以使用write.csv(df, ...
a character string specifying how to deal with embedded double quote characters when quoting strings. Must be one of "escape" (default for write.table), in which case the quote character is escaped in C style by a backslash, or "double" (default for write.csv and write.csv2), in which...

接下来我们看一下read_csv()函数的参数。 read_csv(file, col_names = TRUE, col_types = NULL, col_select = NULL, id = NULL, locale = default_locale(), na = c("", "NA"), quoted_na = TRUE, quote = "\"", comment = "", trim_ws = TRUE, skip = 0, n_max = Inf, guess_m...
问题:使用write.table函数导出数据为.csv格式时,数据全部放入了一个单元格里。 write.table(data,"filename.csv",sep="",row.names = F,col.names = T,quote = F) image.png 原因:没有加sep=参数,.csv格式中以 ,表示分隔。 write.table(data,"filename.csv",quote = F,sep=',') image.png最后...
每一行x中的值都被这个字符串分隔开。 row.names:表示x的行名是否与x一起写的逻辑值,或者是写行名的字符向量 col.names:类似上面。 > write.table(mouse, file = "foo.csv", sep = ",", col.names = NA, + qmethod = "double") 参考资料1:R语言:write.table()函数中文帮助文档(中英文对照)...
不过值得指出的是R语言能够导出的数据格式是有限的,比如在基本包中,我们能够导出数据的格式只有txt,csv。 现在介绍一下两个函数的用法: write.table(x, file = “”, append =FALSE, quote = TRUE, sep = ”“, eol = “\n”, na = “NA”, dec = “.”,row.names = TRUE, col.names = TRUE,...
