R Programming: Save data with different space lengths

Question

I am trying to use R to save the data to a specific format for another analysis software. For example, my data is:

Jane  2  3  0  1
Joe   2  0  1  1
John  1  0  0  0
Jack  2  1  3  1
Jay   0  0  0  0

I would like to save the data to a .txt file in the following format:

Jane  2301
Joe   2011
John  1000
Jack  2131
Jay   0000

If I used write.table(....., sep = "") , there will be no space between the names and numbers. How can I save the file with space only between the name and numbers? Thank you very much!

Answer 1

Jane  2  3  0  1
Joe   2  0  1  1
John  1  0  0  0
Jack  2  1  3  1
Jay   0  0  0  0

d <- read.table(con<-file("clipboard"), header = F)

d1 <- data.frame(col1 = d$V1, 
                 col2 = paste0(d$V2,d$V3,d$V4,d$V5))

write.table(d1, sep = " ", row.names = F)

Answer 2

You will need to change the data format in R before saving it. Here, I am using unite from tidyr to push all of those columns together (it ignores just V1 in this example, combining the rest)

Read sample data:

df <-
  read.table(
    text = 
"
Jane  2  3  0  1
Joe   2  0  1  1
John  1  0  0  0
Jack  2  1  3  1
Jay   0  0  0  0"
  )

Run unite

df %>%
  unite(singleData, -V1, sep = "")

Returns:

    V1 singleData
1 Jane       2301
2  Joe       2011
3 John       1000
4 Jack       2131
5  Jay       0000
