Need to fix up the file having 6 and 7 columns to be read as 6 columns
only. Here is the working. Can somebody please let me know how do I
maintain the order in which rows were read and append the two files into
one:

> count.fields(textConnection("LL1532Ap,ABC# Depot-A+,,1971,8,2
LL1532Ap,ABC# Depot-A+,Bhutan,1971,6,1
LL1532Ap,ABC# Depot-A+,China,1971,17,1
LL1532Ap,ABC# Depot-A+,China,1971,33,1
LL1532Ap,ABC# Depot-A+,,1971,16,2
LL1532Ap,ABC# Depot-A+,,1971,17,1
LL1532Ap,ABC# Depot-A+,HongKong, Asia,1971,22,1
LL1532Ap,ABC# Depot-A+,HongKong, Asia,1971,49,1
LL1532Ap,ABC# Depot-A+,,1971,20,1
LL1532Ap,ABC# Depot-A+,Kazakhstan,1971,27,1
LL1532Ap,ABC# Depot-A+,,1971,33,1
LL1532Ap,ABC# Depot-A+,Kazakhstan, Asia,1973,15,1
LL1532Ap,ABC# Depot-A+,Romania-Europe,1971,10,1
LL1532Ap,ABC# Depot-A+,Romania-Europe,1973,4,1
LL1532Ap,ABC# Depot-A+,Sanchez-America,1973,9,1
LL1532An,ABC# Depot-A-,,1971,8,2"),sep=",",comment.char = "")
 [1] 6 6 6 6 6 6 7 7 6 6 6 7 6 6 6 6

> filName <- "temp.csv"
> nFields <- count.fields(filName, sep = ',', comment.char = "")
> input <- readLines(filName)
> writeLines(input[nFields == 6], con = (file = "6fields.csv"))
> writeLines(input[nFields == 7], con = (file = "7fields.csv"))

> filName <- "7fields.csv"
> length(count.fields(filName, sep = ',', comment.char = "")) -> nFields2
> input <- readLines(filName)
> for (i in 1:nFields2){
 strsplit(input[i],",")[[1]] -> z
 paste (z[1], z[2], paste('"',z[3],',',z[4],'"',sep =' '),
z[5],z[6],z[7],sep = ',') -> input[i]
}
> result <- read.table(textConnection(input), sep = ',')

Need the output to look like
        Sno ID Title Location Year x y 1 LL1532Ap ABC# Depot-A+  1971 8 2 2
