Hi
Good that you have finally got desired result.
Regarding aggregate, you could consult help page
?aggregate
It has many good examples how to use it.
and for understanding factors
?factor is your friend and/or pages 16+ from R intro.
Cheers
Petr

Subject: Re: [R] read txt file - date - no space
Dear Petr,
I have read the file:
MyData <- read.csv(file="obs_prec.csv",header=TRUE, sep=",")
I have used POSIXct to convert properly the date
MyData$date2<-as.POSIXct(MyData$date, format="%m/%d/%Y %H:%M")
creating a second field inside MyDate.
I have converted the -999 to NA:
MyData[MyData== -999] <- NA
dim(MyData):
160008 5
And this is clear because I have 160008 days and 5 field:
date2,date,str1,str2,str3
I have chech the structure of my data:
str(MyData)
'data.frame': 160008 obs. of 5 variables:
$ date : Factor w/ 160008 levels "10/10/1998 0:00",..: 913 914 925 930 931 932 933 934 935 936 ...
$ str1 : num 0.6 0.2 0.6 0 0 0 0 0.2 0.6 0.2 ...
$ str2 : num 0 0.2 0.2 0 0 0 0 0 0.2 0.4 ...
$ str3 : num 0 0.2 0.4 0.6 0 0 0 0 0 0.4 ...
$ date2: POSIXct, format: "1998-10-01 00:00:00" "1998-10-01 01:00:00" "1998-10-01 02:00:00" "1998-10-01 03:00:00" ...
Almost everything is clear:
str1,str2,str3 are mumbers,
date2 are date in the format according to POSIXct: Y-m-d h:m:s
date has 160008 Factor, i.e. 160008 factors which are the number of category.
I do not understand "913 914 925 930" are the possibilitiues in levels?
I have no NA in date2:
which(MyData$date2 == NA)
integer(0)
as well in date.
At this point I have applied:
daily_mean1<-aggregate(MyData$str1, list(format(MyData$date, "%Y-%m-%d")), mean)
which seems to be correct:
I have
dim(daily_mean1):
6667 2
str(daily_mean1)
'data.frame': 6667 obs. of 2 variables:
$ Group.1: chr "1998-10-01" "1998-10-02" "1998-10-03" "1998-10-04" ...
$ x : num 0.1667 0.0583 0.0417 0.3417 0.3333 ...
Really Really thanks:
You not only taught me R but also how to dealwith learning.
Can I ask you anover question about aggregate?
Again thanks
Diego

Thanks,
I have just send you a e-mail, before reading this one.
Let's me read your last mail and go carefully through it.
Thanks again, really really,
I mean it
P.S.
Do you wand my *.csv file?
Not necessarily, you should better learn things yourself if you really want to use R. Only if after you tested all suggested ways and did not get desired result.

Well,
you followed my advice only partly. Did you get rid of your silly -999 values before averaging? Probably not.
Did you tried aggregating by slightly longer construction
aggregate(test[,-1], list(format(test$date, "%Y-%m-%d")), mean)
which keeps difference in month and year? Probably not.
We do not have your data, we do not know what exactly you want to do so it is really difficult to give you a help.
If I calculate correctly there are 24 hour in one day and you have data for 18 years which gives me approximately 158000 distinct values.
I can get either 18 values (averaging years) or aproximately 6600 values (averaging days).
So my advice is:
Read your data to R
Change date column to POSIX but store it in different column
Change NA values from -999 to real NA values
Check dimension of your data ?dim
Check structure of your data ?str
Check if all dates are changed to POSIX correctly, are some of them NA?
Aggregate your values (not by lubridate function day) and store them in another object
Cheers

Subject: Re: [R] read txt file - date - no space
Dear all,
I have found and error in the date conversion. Now it looks like:
MyData <- read.csv(file="obs_prec.csv",header=TRUE, sep=",")
# change date to real
MyData$date<-as.POSIXct(MyData$date, format="%m/%d/%Y %H:%M")
After that I apply the PIKAL's suggestions:
aggregate(MyData[,-1], list(day(MyData$date)), mean)
And this is the final results:
1 -82.43636 -46.12437 -319.2710
2 2 -82.06105 -45.74184 -319.2696
3 3 -82.05527 -45.52650 -319.2416
4 4 -82.03535 -47.59191 -319.2275
5 5 -77.44928 -50.05953 -320.5798
...
31 -86.10234 -47.06247 -340.0968
However, it is not correct.
This because I have not made myself clear about my purpose. As I told you some days ago, I have a *.csv file with hourly data from 10/21/1998 to 12/31/2016. I would like to compute the daily means. Basically, I would like to have the mean of the hourly date for each day from 10/21/1998 to 12/31/2016 and not 31 values.
Really really thanks again,
Diego

I have check the one of the line that gives me problem. I mean, which give NA after R processing. I think that is similar to the others:

@jim: It seems that you suggestion is focus on reading data from the terminal. It is possible to apply it to a *.csv file?
@Pikal: Could it be that there are some date conversion error?
Thanks again,

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

If I could I would like to start again, without mixing strategy and waiting

Here my new file, a *.csv file (buy the way, it is possible to attach it in
