Hello;
I have a problem merging data sets. I use this command:
FileNames <- list.files(path="C:/updated_CFL_Rad_files/2007/11",
full.names=TRUE)
> dataMerge <- data.frame()
> for(f in FileNames){
+ ReadInMerge <- read.csv(file=f, header=T, na.strings="NULL")
+ dataMerge <- merge(dataMerge, ReadInMerge,all=T)
+
+ }
and an error occurs.The size of the data is about 7.5 Mb, I don't know what
does 221 Mb mean!
Error: cannot allocate vector of size 221.6 Mb
In addition: Warning messages:
1: Reached total allocation of 502Mb: see help(memory.size)
2: Reached total allocation of 502Mb: see help(memory.size)
3: Reached total allocation of 502Mb: see help(memory.size)
4: Reached total allocation of 502Mb: see help(memory.size)
