Re: [R] Split a data.frame

Hi! How about this: --- snip -- for (i in 1:(length(split_str)-1)) { assign(paste("DF",i,sep=""),DF[ c((which(DF$name==split_str[i])+1):(which(DF$name==split_str[i+1])-1)), ]) } --- snip --- 'assign' creates for each subset a new data.frame DFn, where n ist a count (1,2,...). But note:

Re: [R] Saving objects in RData file in different name

Hi! Maybe not the most elegant solution, but a workaround is to have a function: > save2<-function(y, ...) { save(y,...)} > save2(x1,x2,file="test.RData") The point is to include the variables to be "renamed" as parameters (in my example: y). The function will use the parameter variable names

Hi! An alternative with 'assign': for ( i in 71:75) {   setwd(paste("C:/Awork/geneAssociation/removed8samples/neuhausen", i, sep=""))   temp.df<-read.csv("seg.pr3.csv", head=T)   temp.df$id<-paste0("sn",i,sep="")   assign(paste0("seg",i,sep=""),temp.df) } rm(temp.df,i)    # Clean up HTH, Kimmo

Re: [R] Importing JSON Files

Hi! Have you tried to use 'fromJSON' with the parameter 'simplifyDataFrame' set to TRUE? See: https://cran.r-project.org/web/packages/jsonlite/vignettes/json-aaquickstart.html -> Section "Data Frames" explains how this affects the data frame structure. IMHO this should solve your problem...

Re: [R] data frame transformation

Hi! Maybe this would do the trick: --- snip --- library(reshape2) # Use 'reshape2' library(dplyr)# Use 'dplyr' datatransfer<-data %>% mutate(letter2=letter) %>% dcast(id+letter~letter2, value.var="weight") --- snip --- Or did I misunderstood something? Best, Kimmo 2019-01-06, 13:16
