converting character value to numeric

[Adi27]

Hi my code is showing an error of not being able to find the values:

/* New dataset for available products */
data AvailableProducts;
set Qed.Products;
where available = 'T';
run;

/* New dataset for unavailable products */
data UnavailableProducts;
set Qed.Products;
where available = 'F';
run;

/* New dataset for converting grams and rating to numeric values */
Data Qed_Converted;
Set Qed.Products;
rating_num = input(rating, best32.);
grams_num = input(grams, best32.);
run;

/* Descriptive Statistics for available products */
PROC MEANS DATA=AvailableProducts;
VAR grams price rating;
OUTPUT OUT=AvailableStats
MEAN=Avg_grams Avg_price Avg_rating;
RUN;

I have converted the character values to numeric still it is showing this!

If you are getting errors in the log, show us the ENTIRE log.

Otherwise, I don't know what this is referring to.

this is the log: 88 /* Descriptive Statistics for available products */
89 PROC MEANS DATA=AvailableProducts;
90 VAR grams price rating;
ERROR: Variable grams in list does not match type prescribed for this list.
ERROR: Variable price in list does not match type prescribed for this list.
ERROR: Variable RATING not found.
91 OUTPUT OUT=AvailableStats
92 MEAN=Avg_grams Avg_price Avg_rating;
93 RUN;

NOTE: The SAS System stopped processing this step because of errors.
WARNING: The data set WORK.AVAILABLESTATS may be incomplete. When this step was stopped there were 0 observations and 0 variables.

Your converted variables are in dataset qed_converted (with a _num suffix), but you use dataset availableproducts in the PROC MEANS.

You can streamline your process a lot:

data
  availableproducts
  unavailableproducts
;
set qed.products;
rating_num = input(rating,best32.);
grams_num = input(grams,best32.);
ptice_num = input(price,best32.);
drop rating grams price;
rename
  rating_num=rating
  grams_num=grams
  price_num=price
;
select (available);
  when ("T") output availableproducts;
  when ("F") output unavailableproducts;
end;
run;

proc means data=availableproducts;
var grams price rating;
output
  out=availablestats
  mean=avg_grams avg_price avg_rating
;
run;

But you should first ask yourself why the conversions are needed in the first place. Numbers stored in character variables point to a faulty import process which brings the data into SAS, e.g. using a bad medium (Excel files) or PROC IMPORT.
