[R] sqldf not joining all the fields

[David Winsemius]

You have now given two different assignments to x_data and none to  
y_data:

The str( from the file access offering:

 > str(x_data)
'data.frame':	2848 obs. of  5 variables:
  $ item_code       : int  100 110 150 160 161 164 200 210 212 220 ...
  $ name            : chr  "NEONACLEX K" "NEONACLEX" "MESORB"  
"ABSORBENT CELLULOSE MESO" ...
  $ formulation_code: chr  "TABS" "TABS" "DRESS" "DRESS" ...
  $ strength        : chr  "NULL" "5MG" "10CMX10CM" "10CMX10CM" ...
  $ bnf_code        : chr  "2.2.8" "2.2.1" "20.3.1" "20.3.1" ...

The str from assignment from the dput offering
 > str(x_data)
'data.frame':	10 obs. of  10 variables:
  $ prochi         : chr  "CAO0000713" "CAO0000713" "CAO0000713"  
"CAO0000713" ...
  $ prescribed_date: chr  "22/06/2001" "28/04/2000" "10/04/2000"  
"03/07/2000" ...
  $ dataMonth      : chr  "NULL" "NULL" "NULL" "NULL" ...
  $ item_code      : chr  "842752" "7800" "842652" "842652" ...
  $ res_seqno      : chr  "NULL" "NULL" "NULL" "NULL" ...
  $ quantity       : chr  "60" "100G" "60" "60" ...
  $ directions     : chr  "1/D" "A/TD" "1/D" "1/D" ...
  $ no_of_packs    : chr  "NULL" "NULL" "NULL" "NULL" ...
  $ datasource     : chr  "TSF" "TSF" "TSF" "TSF" ...
  $ scan_ref_no    : chr  "NULL" "NULL" "NULL" "NULL" ...

This code "worked", but it is not clear that the x-y assignments were  
correct:

x_data <- read.table(file="http://n4.nabble.com/file/n1590804/feb09_267_presc_items_tsf.txt 
", header = TRUE, sep = "|", quote = "\"'",
                dec = ".",as.is = TRUE,na.strings = "NA",colClasses =  
NA,
nrows = 3864284,
                skip = 0, check.names = TRUE,fill=TRUE,
                strip.white = TRUE, blank.lines.skip = TRUE,
                comment.char = "#", allowEscapes = FALSE, flush = FALSE,
                fileEncoding = "", encoding = "unknown")
