Hi again, I was trying to read a subset of Data from a CSV file using below code as example :
library(sqldf) Dat = structure(list(`col 1` = c(133261L, 133261L, 133262L, 133262L ), `col 2` = structure(1:4, .Label = c("aaa1", "aaa2", "bbb1, bbb", "bbb3, bbb"), class = "factor"), `col 3` = c(10.59, 10.56, 10.59, 10.56), `col 4` = c(10.59, 10.56, 10.59, 10.56), `col 5` = c(10.59, 10.56, 10.59, 10.56), `col 6` = structure(c(1L, 2L, 1L, 2L), .Label = c("04-Jul-16", "05-Jul-16"), class = "factor")), .Names = c("col 1", "col 2", "col 3", "col 4", "col 5", "col 6"), class = "data.frame", row.names = c(NA, -4L)) Dat write.csv(Dat, "Dat.csv", quote = FALSE, row.names = FALSE) ReadName = '133261' read.csv.sql("Dat.csv", sql = "select * from file where 'col 1' = ReadName") Loading required package: tcltk Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : line 1 did not have 7 elements This code generates above Error. Could you please help me with a pointer where something went wrong? My actual CSV file is quite huge so I cant read it as whole. However basic structure of my original file is similar as above "Dat" Thanks for your time. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
