Using IF Statements on Vectors in R -

-

so i'm trying code fraud detection algorithm using r. have numerical value (fraudval) proportional how user committing fraud in vector. how create new column state if it's high, medium, or low, given sensitivity of 'fraudval' (i.e. if 0.6 > 'fraudval' > 0.3, it's low, if in between 0.6 , 0.8 med, , and high if it's 0.8 or higher.

here input , expected output

sensitivities are: low - 0, low - 0.3, medium - 0.6, high - 0.8

input (df):

id fraudval 1  0.4 2  0.8 3  0.2 4  0.6

output (df):

id fraudval test 1  0.4      low 2  0.8      high 3  0.2      low 4  0.6      medium

thanks in advance! :d

i use cut:

r> df$test <- cut(df$fraudval, c(0,.3,.6,.8,inf), +                c("very low", "low", "med", "high"), right=false) r> d   id fraudval     test 1  1      0.4      low 2  2      0.8     high 3  3      0.2 low 4  4      0.6      med

i got string (str1) , want extract after pattern "mycode=", local str1 = "servername/codebase/?mycode=abc123"; local tmp1 = string.match(str1, "mycode=%w+"); local tmp2 = string.gsub(tmp1,"mycode=", ""); from logs, tmp1 => mycode=abc123 tmp2 => abc123 is there better/more efficient way this? belive lua strings not follow posix standard (due size of code base). yes, use capture in pattern control string.match . from lua reference manual (emphasis mine): looks first match of pattern in string s. if finds one, match returns captures pattern ; otherwise returns nil. if pattern specifies no captures, whole match returned. third, optional numerical argument init specifies start search; default value 1 , can negative. it works this: > local str1 = "servername/codebase/?mycode=abc123" > local tmp1 = string.match(str1, "mycode=%w+") > print(tmp1) mycode=abc123 > local tmp2 =...
