Hi all,
I'm trying to compress a data like "<= 0.3" to "0.3", but COMPRESS FUNCTION seems that just can compress ALL punctuation marks at one time...So, is there any better way to compress only "<= " and keep the decimal?
However, this is just one example of my data. I need a resolution for all cases like this. Thank you!
Original Compressed
<= 0.3 0.3
0.58 0.58
> 1.2 1.2
45 45
Well, its likely that you have other maths symbols, so maybe reverse the thinking, the below "k"eeps, only "d"igits and the decimal:
data test; original = "<= 0.3"; compressed = compress(original,'.','kd'); run;
data test;
original = "<= 0.3";
compressed = compress(original,'<=');
run;
proc print data=test;
run;
works.
Output:
Obs original compressed 1 <= 0.3 0.3
Hi @JohnChen_TW;
You can use this line :
compressed = compress(original,'<=');
this will remove <= combination from the variaable;
But, on the third line you provided another special character in sample data,
so below code will not compress this special character;
so in this case you can use this code:
data test;
set test;
compressed=compress(original,'<');
compressed=compress(original,'=');
compressed=compress(original,'>');
run;
it will remove all the possible combination like: <=, <, =, >, => from the variable

data test; original = "<= 0.3"; compressed = compress(original,'.','kd'); run;
