i have two data frames which are cleaned and merged as a single csv file , the data frames are like this
**Source Master** chang chun petrochemical CHANG CHUN GROUP chang chun plastics CHURCH AND DWIGHT CO INC church dwight CITRIX SYSTEMS ASIA PACIFIC P L citrix systems pacific CNH INDUSTRIAL N.V
now from these , i have to consider the first name and check with each name of master names and find a match that is relevant and print the output as another data frame. the above data frames are few , but i am working with 20k values as such.
My output must look like this
**Source Master Result** chang chun petrochemical CHANG CHUN GROUP CHANG CHUN GROUP chang chun plastics CHURCH AND DWIGHT CO INC CHANG CHUN GROUP church dwight CITRIX SYSTEMS ASIA PACIFIC P L CHURCH AND DWIGHT CO INC citrix systems pacific CNH INDUSTRIAL N.V CITRIX SYSTEMS ASIA PACIFIC P L
I tried this with possible ways with this link Merging through fuzzy matching of variables in R but , no luck so far..!
Thank in advance!!
when i use the above code for large set of data , the result is this-
code used:
Mast <- pmatch(Names$I_sender_O_Receiver_Customer, Master.Names$MOD, nomatch=NA)
OUTPUT
NA NA 2 3 NA NA NA 6 NA NA 9 NA NA NA 12 NA NA NA 13 14 15 16 NA 18 19 20 21 22 NA 24 NA 26 NA 28 NA NA NA 30 NA NA 33 NA 35 36 37 NA 39 40 NA NA 43 NA 45 46 NA 48 49 50 51 52 53 54 55 56 57 58 NA [68] 60 61 62 NA NA NA NA 64 NA 66 67 68 69 70 71 72 73 NA 75 76 77 78 NA 79 80 81 NA 83 84 85 86 87 88
CODE:
Mast <- sapply(Names$I_sender_O_Receiver_Customer, function(x) { agrep(x, Master.Names$MOD,value=TRUE) })
OUTPUT:
[[1]] character(0) [[2]] character(0) [[3]] [1] " CHURCH AND DWIGHT CO INC" [[4]] [1] " CITRIX SYSTEMS ASIA PACIFIC P L" [[5]] character(0)
and even with for loop no result is produced.
code:
for(i in seq_len(nrow(df$ICIS_Cust_Names))) { df$reslt[i] <- grep(x = str_split(df$ICIS_Cust_Names[i]," ")[[1]][1], df$Master_Names[i],value=TRUE) } print(df$reslt)
Code 2: Used for loop just for 100 rows
for (i in 100){ gr1$x[i] = agrep(gr1$ICIS_Cust_Names[i], gr2$Master_Names, value = TRUE, max = list(del = 0.2, ins = 0.3, sub = 0.4)) gr2$Y[i] = agrep(gr1$ICIS_Cust_Names[i], gr2$Master_Names, value = FALSE, max = list(del = 0.2, ins = 0.3, sub = 0.4)) }
Result:
NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA
Error
Error in `$<-.data.frame`(`*tmp*`, "x", value = c(NA, NA, " church dwight " : replacement has 3 rows, data has 100
when observed the result for above is considered , as it checks directly with the row value of each data frames , but i want it to consider first element of Source and check with all the elements of master and come up with a match , likewise for rest. I would appreciate if someone could correct my code ! thanks in advance..!
