Re: [R] read.table but more tables at once

2009-10-28 Thread baptiste auguie 
Hi,

Try this,

files - paste(RA94010,1:3,sep=)
# or files - list.files(pattern = RA94010)

list.of.data - lapply(files, read.table, header=F)

# if required, collapse into a single data.frame
do.call(rbind, list.of.data)


HTH,

 Dear all,

 I have a lot of data files (.txt) that I want to read in all at once, if
 possible.
 the files have names in time system. for example: RA940101, RA940102,
 RA940103, RA940104 an so on.
 (meaning: RA, year:91, month: here january, day of the month.)

 I tried something like

 vektor - c(RA940101,RA940102,RA940103)

 for (x in 1:3)
 { data - read.table(paste(vektor[x],sep=),header=F) }

 But how can I put the vektor on the left side, so that data would be instead
 of data the three first days of the year 1994?

 best wishes and thanks a lot for your answers,

 Sybille

 Store in a list:

data = list()
 for(x  in 1:3){
   data[[vektor[x]]] = read.table(...)
}

 then you can do data[[RA940101]] to get that set of data.

 You can also do this by number:

 data[[x]] = read.table()

 and then get data[[1]], data[[2]] etc etc.

See any basic R help/tutorial for more information about 'lists'.
