sessionInfo at end of message. I have data that I was given as an Excel .xlsx file. It contains 96266 lines and 24 columns. I opened it in OpenOffice.org and saved it in .csv format, using the pipe character as a field separator. This produced a file with 96266 lines.
When I read it into R thusly: > skip0.dd <- read.csv("AmbulanceDispatches2017-2019-02-18-2020.csv", sep = "|", header = TRUE, comment.char = "", skip = 0) the resulting skip0.dd dataframe has only 58208 lines: > dim(skip0.dd) [1] 58208 24 I've tried a variety of things to troubleshoot. Using head() and tail(), the expected first and last lines (comparing to the .csv file) do indeed exist in skip0.dd. Several arbitrary lines from the "middle" of the csv file are also present in the skip0.dd dataframe. I tried reading only the first column, which is integer, but still it appears that not all lines are read in: > classes <- c(NA, rep("NULL", 23)) > skip01.dd <- read.csv("AmbulanceDispatches2017-2019-02-18-2020.csv", sep = "|", header = TRUE, comment.char = "", skip = 0, colClasses = classes) > dim(skip01.dd) [1] 58208 1 Skipping the first 50000 lines nominally should give me a dataframe of 46266 lines, or at least one of 50000 fewer lines than skip0.dd (i.e. 8208 lines), but it does neither: > skip50000.dd <- read.csv("AmbulanceDispatches2017-2019-02-18-2020.csv", sep = "|", header = TRUE, comment.char = "", skip = 50000) > dim(skip50000.dd) [1] 22170 24 Any thoughts on what might be going wrong? Some funky characters from Excel or OpenOffice.org lurking in the .csv file? Perhaps I'd have more success with one of the packages that enables reading directly from an .xlsx file.
