A list of data frames and a list of colnames.
I have a list of file names, and a list of data frames contained in those files.
mynames <- list.files()
mydata <- lapply(mynames, read.delim)
Every file contains two columns.
> colnames(mydata[[1]])
[1] "Name" "NumReads"
> colnames(mydata[[2]])
[1] "Name" "NumReads"
I can set the colnames easily enough with a for loop.
for (i in seq_along(mynames)) {
colnames(mydata[[i]])[2] <- mynames[i]
}
Is there a nicer way to do this?

Return a list from a .Call but segfaults
...There 2*I such pairs( (Ki,KDatai), (Vi,VDatai))
The numbers Ki(and Vi) are written in network order.
I am returning a list of I elements each element a list of two
elements corresponding to KData and VData (which are serialized R
objects) .
ll <- .Call("returnListOfKV", rawkv, numread)
When use the function with browser(), and type head(ll) i get valid
results.
However, i get a segfault when the code runs the next line
j <- append(j,ll)
(where j was defined as vector(mode='list') )
The code below looks alright, but it appears to crash when getting
copied.
