Dear R users:
I'm trying to generate a output file with fixed format using function "sprintf"
in R. However, the execution time in R is very long even the toy data (smaller
size df) seems to work fine. The syntax that I used is as follows:
df.fmt <- sprintf("%2s%2s%2.4f", df$v1, df$v2, df$v3)
write.table(df.fmt, output.name,...)
The actual dataset is a df with the dimention of 67944 by 34. I'm wondering
whether there is an elegant way of doing it. I would like output in a txt file.
Many thanks.
