This discussion is a bit weird so can we step back.
Someone wants help on how to read in a file that apparently was not written
following one of several consistent sets of rules.
If it was fixed width, R has functions that can read that.
If it was separated by commas, tabs, single spaces,
It looks like we can look at the last digit of the data and that would
be the column number; is that correct?

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

This gets it into a data frame. If you know which columns should be numeric you
can convert them.
s <-
"x1 x2 x3 x4
1 B22
2 C33
322 B22 D34
4 D44
51 D53
60 D62
"
tc <- textConnection( s )
lns <- readLines(tc)
close(tc)
if ( "" == lns[ length(
Let us take the max space is two and the output should not be fixed
filed but preferable a csv file.

Messed up did not see your 'desired' output which will be hard since there
is not a consistent number of spaces that would represent the desired
column number. Do you have any hit as to how to interpret the spacing
especially you have several hundred more lines? Is the output supposed to

That is my problem. The spacing between columns is not consistent. It
may be single space or multiple spaces (two or three).

You said the column values were separated by space characters.
Copying the text from gmail shows that some column names and column
values are separated by single spaces (e.g., between x1 and x2) and
some by multiple spaces (e.g., between x3 and x4. Did the mail mess
up the spacing or is there
I Tried that one and it did not work. Please see the error message
Error in read.table(text = "x1 x2 x3 x4\n1 B12 \n2 C23

Since the columns in the file are separated by a space character, " ",
add the read.table argument sep=" ".

Oh wow.

Where's the like button?
Note, I was able to rewrite it without the deprecated args.
(Don't want one of those CRAN emails, in 12 months from now, saying
please change ).
I'll have to come back to this later, to see if I can get the body of
f() to access the slot
Hi all, I am trying to read a messy data but facing difficulty. The
data has several columns separated by blank space(s). Each column
value may have different lengths across the rows. The first
row(header) has four columns. However, each row may not have the four
column values. For
yes, good idea, eventually here's what I will do:
time(DF.w) <- as.POSIXlt(time(DF.w))$sec
myticks <- round(pretty(time(DF.w)),6)
mylabels <- as.character(formatC(myticks,format =
"f",digits=6,width=9,flag=" "))
xyplot( DF.w
, xlab = paste0("Seconds from ",format(mystart,"%Y-%m-%d
Try changing your repository from Melpa to Melpa-stable:
(add-to-list 'package-archives
'("melpa-stable" . "https://stable.melpa.org/packages/;) t)
I had a similar problem after a recent update of ESS in MELPA, but
after I deleted ESS and reinstalled from melpa-stable, everything
Also, it might be better to simply use seconds as the time. In that
case both plot and xyplot run without error.
time(DF.w) <- as.POSIXlt(time(DF.w))$sec
# now run plot or xyplot as before

I assume that this is a lattice problem. Replacing xyplot with plot
and using all the same arguments there is no error.

That monday does not exist. FOr the week before:
strptime(paste0("2020-52","-1"),format="%Y-%W-%u")
[1] "2020-12-28"
One week later is no longer in 2020, so there is no 53th week.

Thanks Uwe and Bert,
I got the essential now, and can manage. Date handling stays quite a
challenge with a variable number of weeks in a year, but I can
understand why. Means eye-control (or NA detection) of strptime
conversion stays necessary...

Dear R-Help-List,
I have to process time series with a sampling frequency of 1 MHz.
I use the POSIXct format for the date-times with microsecond in a zoo
object and the xyplot.zoo function to do the graphs.
As I show in the below example I had a trouble to plot the labels on the
x-axis with
I think the relevant info from ?strptime is:
"For strptime the input string need not specify the date completely: it is
assumed that unspecified seconds, minutes or hours are zero, and an
unspecified year, month or day is the current one. (However, if a month is
specified, the day of that month

Sorry to answer to myself, but the format was clearly incorrect in the
previous post. It should read, refering to the 1th day of the week:
strptime(paste0(mydate,"-1"),format="%Y-%W-%u")
It converts better, but with a NA on week 53

Dear all,
I have a trouble trying to convert dates given in character to POSIX.
The date is expressed as a year then the week number e.g. "2020-01"
(first week of 2020). I thought is can be converted as following:
strptime(mydate,format="%Y-%W")
%W refering to the week of the year as decimal
29 matches
