Using seq function, you need to following two steps: Step-1 Generate sequence from 2 to 10 using following code: a<-seq(from=2,to = 10) Step-2 Generate sequence from 10 to 2 using following code: b<-seq(from=9,to = 2) Now, combine above two results using following code: data<-c(a,b) The output should as follow: > data [1] 2 3 4 … Read more
See this df<-data.frame(V1=c(“m h j i d a”,”j h o f k l”,”g k o d m a”)) unique(unlist(apply(df,1,strsplit,split=” “))) 8 solved Getting unique values in R [closed]
We could split the dataset (‘df’) with ‘1416’ columns to equal size ‘118’ columns by creating a grouping index with gl lst <- setNames(lapply(split(1:ncol(df), as.numeric(gl(ncol(df), 118, ncol(df)))), function(i) df[,i]), paste0(‘site’, 1:12)) Or you can create the ‘lst’ without using the split lst <- setNames(lapply(seq(1, ncol(df), by = 118), function(i) df[i:(i+117)]), paste0(‘site’, 1:12)) If we need … Read more
