csv files error in R - r

Question

When trying to read a local csv file im getting the error
Error in xts(dat, order.by = as.Date(rownames(dat), "%m/%d/%Y")) :
'order.by' cannot contain 'NA', 'NaN', or 'Inf'
im trying out the example from https://rpubs.com/mohammadshadan/288218 which is the following:
tmp_file <- "test.csv"
# Create dat by reading tmp_file
dat <- read.csv(tmp_file,header=FALSE)
# Convert dat into xts
xts(dat, order.by = as.Date(rownames(dat), "%m/%d/%Y"))
# Read tmp_file using read.zoo
dat_zoo <- read.zoo(tmp_file, index.column = 0, sep = ",", format = "%m/%d/%Y")
# Convert dat_zoo to xts
dat_xts <- as.xts(dat_zoo)
the thing is when i try to read the file like in the example which is reading the file from the server this works somehow but not when i try with a csv file locally even if its the same info as the file in the web.
i have tried creating the csv file with Notepad,Notepad++ and Excel with no luck.
Any idea what im missing?, i have also tried using read.table instead of csv with the same results...
File can be found at: https://ufile.io/zfqje
if header=TRUE i get the following error:
Warning messages: 1: In read.table(file = file, header = header, sep =
sep, quote = quote, : incomplete final line found by
readTableHeader on 'test.csv'
2: In read(file, ...) : incomplete
final line found by readTableHeader on 'test.csv'

Answer 1

The problem is the header=FALSE argument in read.csv.
read.csv will choose the first column as the row names if there is a header and the first row contains one fewer field than the number of columns. When header = FALSE, it doesn't create the row names.
Here is an example of the problem:
dat <- read.csv(text = "a,b
1/02/2015,1,3
2/03/2015,2,4", header = F)
as.Date(rownames(dat), "%m/%d/%Y")
#> [1] NA NA NA
By removing header = F, the problem is fixed:
dat <- read.csv(text = "a,b
1/02/2015,1,3
2/03/2015,2,4")
as.Date(rownames(dat), "%m/%d/%Y")
#> [1] "2015-01-02" "2015-02-03"
