SAS : Convert character to numeric without creating another variable


SAS : Convert character to numeric without creating another variable

seems to work fine As noted elsewhere, you do need to use a second variable. SAS won't let you alter the variable type of a column directly, but you can cheat things by using rename in a similar way as above.
The one thing I'm going to suggest different from NEOmen's answer or yours above is using input. Length/assignment or using the *1 method are both fine, but they rely on SAS's automatic type conversion, which will add a note to your log that it's doing it. You should avoid things like that in your log, as they are messy and make others think you may have done it on accident.
code :
data test1;
  set test(rename=x=x_old);
  x=input(x_old,best12.); *whatever is appropriate informat for your variable;
run;

I think the issue was by ths following , You'll have to do this in two steps:
Extract the characters "244.1"
code :
var2 = substr(var1, 13, 6);
var3 = input(var2, 8.); 
data work.one;

   var1 = "census tract 244.1";
   var2 = substr(var1, 13, 6);
   var3 = input(var2, 8.);

run;

/* Show that var3 is a numeric variable */
proc contents data=work.one;
run;
drop var1;
rename var3=var1;

it should still fix some issue The easy way to do it (if you know the specific date format) is to use the input function. 09:27 If put(input(var,??yymmdd10.),yymmdd10.)=var then its a date!
code :
else if input(var,best.) ne . then its a number.

Otherwiseits a character string.

like below fixes the issue We can use type.convert from base R by looping over the columns of the dataset and assign it back to the original object
code :
df[] <- lapply(df, function(x) type.convert(as.character(x), as.is = TRUE))
str(df)
#'data.frame':   4 obs. of  3 variables:
#$ var1 : int  1 2 3 4
#$ var2 : int  1 2 3 4
#$ chrOK: chr  "rick" "summer" "beth" "morty"

may help you . If you are sure that all rows are strictly numeric, run this alter statement.
code :
ALTER TABLE yourtable modify ( PDS NUMBER );
ALTER TABLE yourtable  ADD (PDS_temp NUMBER);
UPDATE yourtable SET PDS_temp  = to_number(PDS);
--Dont proceed if the above statement fails.

ALTER TABLE yourtable   DROP COLUMN PDS;
ALTER TABLE yourtable  RENAME COLUMN PDS_temp TO PDS;

I hope this helps you . I have a monthly data on sales volumes:
code :
data$date = lubridate::ymd(paste(data$YearMonth, 1))

library(ggplot2)
ggplot(data, aes(date, Sales_Count)) + 
  geom_line() +
  scale_x_date(date_breaks = "month",
               date_labels = "%Y %b")
