How to read a tab delimited file in R when data row contains an extra separator at end of line? -


i'm trying read file has annoying problem. header has 5 columns data has 6 due tab character @ end of line data rows. confused r , put item code row name , data not shifted 1 position. 

> items <- read.csv("http://download.bls.gov/pub/time.series/cu/cu.item", sep = "\t") > items[1,]                item_code item_name display_level selectable sort_sequence aa0 items - old base         0          true          2            na > row.names(items[1,]) [1] "aa0"

any idea how fix this? if specify row.names = null, read in item code "row.names" column still shifted.

> items <- read.csv("http://download.bls.gov/pub/time.series/cu/cu.item", sep = "\t", row.names = null) > items[1,]   row.names            item_code item_name display_level selectable sort_sequence 1       aa0 items - old base         0          true          2            na

as mentioned in comment, can try read in file without first line , add headers in later.

something like:

read.table("http://download.bls.gov/pub/time.series/cu/cu.item",             header = false, skip = 1,             col.names = c(              scan("http://download.bls.gov/pub/time.series/cu/cu.item",                    = "", n = 5), "xxxxx"),             sep = "\t")[-6]

the [-6] drop column of na values.

here's above:

head(   read.table("http://download.bls.gov/pub/time.series/cu/cu.item",               header = false, skip = 1,               col.names = c(                scan("http://download.bls.gov/pub/time.series/cu/cu.item",                      = "", n = 5), "xxxxx"),               sep = "\t")[-6]) # read 5 items #   item_code                                          item_name display_level # 1       aa0                               items - old base             0 # 2      aa0r purchasing power of consumer dollar - old base             0 # 3       sa0                                          items             0 # 4      sa0e                                             energy             1 # 5     sa0l1                                items less food             1 # 6    sa0l12                    items less food , shelter             1 #   selectable sort_sequence # 1       true             2 # 2       true           399 # 3       true             1 # 4       true           374 # 5       true           358 # 6       true           361
