Hello R user,
I have four data sets in dir "D:/Bharat Warule/Rdata_file" which are
output_data_prod_1.rda, output_data_prod_2.rda, output_data_prod_3.rda,
output_data_prod_4.rda.
Each data set is huge size like number of rows 343297 and columns are near
to 50.
For example:
x1<- data.frame(x11=c(1,2,3,4,5),x112=c(10,10,10,10,10))
x2<- data.frame(x11=c(1,2,3,4,5),x122=c(20,20,20,20,20))
x3<- data.frame(x11=c(1,2,3,4,5),x132=c(30,30,30,30,30))
x4<- data.frame(x11=c(1,2,3,4,5),x142=c(40,40,40,40,40))
x5<- data.frame(x11=c(1,2,3,4,5),x152=c(50,50,50,50,50))
for(i in 1:5){
name<- paste('x',i,sep='')
name1<- paste(name,"rda",sep='.')
save(name, file = name1)
To fix this part, use:
save(list = name, file = name1)
}
I want merge this data sets into one data set but I don’t know where I am
going wrong?
Please help me. Thanks for your help.
subsetname<- "x1"
file_no<- 4
output_data_prod<- data.frame()
for(n in 1:file_no){
myfile<- gsub("( )", "", paste(subsetname , "_", n,".rda"))
To match the above:
myfile <- gsub("( )", "", paste(subsetname , n, ".rda", sep=""))
temp_data<- load(file = myfile)
data_22<- get(temp_data)
if(dim(output_data_prod)[1]==0){output_data_prod<- data_22
}else{
output_data_prod<- merge(inData1 = output_data_prod,
Nonsense, the arguments of merge are called x and y rather than inData1
and inData2.
Uwe Ligges
inData2 = data_22 ,type = "inner", all=FALSE ,
by =c("x11"))}
