Dear All: I am trying to load an R data set, but I got the following message. Please see below. The file is there. setwd("F:/Fall_2017/5-STA574/2-Notes/1-R/1-R_new/chapter4-Entering_Data") datahs0csv <- read.table("hs0.csv", header=T, sep=",") attach(datahs0csv) detach(datahs0csv) rm(list=ls()) Then I tried to reload the data, but I got this error message. I am not sure what was wrong. *> load("datahs0csv.rda")* Error in readChar(con, 5L, useBytes = TR...

Dear All: It was saved, but there was a space somewhere. So it works for me now. I do have another similar problem. I saved an R data file save(datahs0csv,file=" F:\Fall_2017\5-STA574\2-Notes\1-R\1-R_new\chapter4-Entering_Data/datahs0csv2 .rda") *The new R data file "*datahs0csv2.rda*" is in the directory.* I tried to load the file "" to R, but I got an error message. Please see below. > *load(file="F:/Fall...

Hi Abou, You haven't saved the datahs0csv. When you are done manipulating datahs0csv you can use save(datahs0csv, file = 'datahs0csv.rda'). Then you should be able to load the data.

The object you load has the same name as the object you saved. In this case datahs0csv and not the name of the file sans .rda On Di., 12.

...lve, see some examples: https://github.com/discoleo/R/blob/master/Math/Systems.NLE.Tutorial.md https://github.com/discoleo/R/blob/master/Math/Systems.Lambert.R I did solve much more complex ones, for a monster see: https://github.com/discoleo/R/blob/master/Math/Poly.System.S5.Ht.Formulas.Derivation.HS0.R [and the remaining Poly.System.S5.Ht... scripts] I presume that only the real roots are required (it's possible to solve systems with complex roots as well). I can provide further details as well. Sincerely, Leonard [[alternative HTML version deleted]]
