R help - Jun 2017 - Request for help - adding text files to a data frame

Hello Everyone,

I have a data frame which looks something like this:

    V1 <-c(1,2,3)
    V2 <-c(5,6,7)
    V3 <-c(9,10,11)

     df <- data.frame(V1,V2,V3)

I want to add couple of text files at the beginning of df and save
the df as a csv file.


The csv file should look something like this:

"AAAAAAAA"
"BBBBBBBBB"
"CCCCCCCCC"
V1  V2 V3
1    5  9
2    6   10
3    7   11


Any suggestions/advice in this regard.

Thanks for your help,
Bhaskar

You appear to either be ignorant of the structure pf data frames or
have not expressed yourself clearly enough (for me, anyway). Please go
through a tutorial to learn about the fixed structure of data frames,
for which your request does not appear to reflect an understanding.

Cheers,
Bert

Why exactly would that be called a csv file? (It has no commas.)

At any rate discrepancies like that get resolved in favor of the example and my
suggestion would be:

First look carefully at:

?write.table   # and read all the Arguments and Details sections

... as well as following all of the links from that help page that appear just
above the Examples.

write(c("AAAAAAAA",
"BBBBBBBBB",
"CCCCCCCCC"), file="test.txt")
write.table(df, file="test.txt",
append=TRUE,quote=FALSE,row.names=FALSE)

Hi Bhaskar,
You can put all sorts of stuff into a text file simply by using the
"sink" command:

sink("bm.txt")
cat("AAAAAAAA\n")
B9<-"BBBBBBBBB"
cat(B9,"\n",sep="")
for(i in 1:9) cat("C")
cat("\n")
print(df)
sink()

What you intend to do with a file like this is beyond me.
