Hi Kathan,
This is a very lazy answer as I haven't tested it. I think you will
need to wrap your loop in a function and return the modified list_df
to assign it like this:
add_IDs<-function(xdf) {
for(i in seq_along(xdf)) {
xdf$position_tab_[[i]]$ID <-
unlist(lapply(xdf$position_tab_[[i]]$mi
I have been trying to run a forloop for a function that compares dataframe n
with dataframe n-1, across a list of dataframes. It does this by checking
each midpoint of dataframe n with each midpoint of dataframe n-1. This is
done to make up for an disparity in row length. The idea of this code is t
Alexandra,
According to the documentation (?readLines), readLines returns a character
vector with one line from the file being read in each element of the vector.
You can put the character vector from each file (as represented by a year
designation in your example) in a separate list element. Y
Hello,
Try the following.
Data <- lapply(sprintf('file/%4i', 2000:2003), readLines)
This will give you a list with 4 elements, each of which is the contents
of each file.
Hope this helps,
Rui Barradas

Hi,
I need help with a for loop and printing data. I want to loop through a
few years and print the data from each year stacked on top of each other.
For example,
for (i in 2000:2003){
#script for downloading each year
Data = readLines(sprintf('file/%4i,i))
}
It only prints out the data from th

Hi,
I would like to loop a specific code through multiple files ending in .CDF in
the same directory, but I am unsure of how to do that (new to R).
Can someone please help me with this-thank you.
This is the code I would like to loop:
