[R] Error in reading subset of data from CSV file

Hi again, I was trying to read a subset of Data from a CSV file using below code as example : library(sqldf) Dat = structure(list(`col 1` = c(133261L, 133261L, 133262L, 133262L ), `col 2` = structure(1:4, .Label = c("aaa1", "aaa2", "bbb1, bbb", "bbb3, bbb"), class = "factor"), `col 3` = c(10.59,

Hi Bailey, Treat it as a guess, but try this: for (i in c(1:3)){ y<-mydata[,i] x <- mblm(y ~ Year, mydata, repeated = FALSE) print(x) } I'm not sure that you can mix indexed columns with column names. Also, Year is column 4, no? Jim On Sun, Sep 4, 2016 at 11:43 AM, Bailey Hewitt wrote: > H

Hi Christofer, You have embedded commas in your data structure. This is guaranteed to mess up a CSV read. Jim On Sun, Sep 4, 2016 at 5:54 PM, Christofer Bogaso wrote: > Hi again, > > I was trying to read a subset of Data from a CSV file using below code > as example : > > library(sqldf) > > Dat

A useful rule is to fix the first error you understand and hope that the others go away. On 04/09/2016 04:05, Tamar Michaeli wrote: Any help in resolving the following errors will be appreciated: pollutantmean <- function(directory, pollutant, id=1:332) + file_inc <- list.files("specdata", f

The "c" function creates vectors. Rows of data frames are data frames, not vectors. new_row <- data.frame( Prod_name = "Day_name", `Date 1`=1, `Date 2`=2,`Date 3`=3 ) data_may <- rbind( new_row, data_may ) Furthermore, data frames are NOT spreadsheets. "Day_num" looks suspiciously UNlike a
