I have a data set like below:
Country Region Molecule Item Code
IND NA PB102 FR206985511
THAI AP PB103 BA-107603 / F000113361 / 107603
LUXE NA PB105 1012701 / SGP-1012701 / F041701000
IND AP PB106 AU206985211 / CA-F206985211
THAI HP PB107 F034702000 / 1010701 / SGP-1010701
BANG NA PB108 F000007970/25781/20009021
I want to split based the string values in ITEMCODE column on / and create a new row for each entry.
For instance, the desired output will be:
Country Region Molecule Item Code New row
IND NA PB102 FR206985511 FR206985511
THAI AP PB103 BA-107603 / F000113361 / 107603 F000113361
107603
BA-107603
LUXE NA PB105 1012701 / SP-1012701 / F041701000 1012701
SP-1012701
F041701000
IND AP PB106 AU206985211 / CA-F206985211 AU206985211
CA-F206985211
THAI HP PB107 F034702000 / 1010701 / SP-1010701 F034702000
1010701
SP-1010701
BANG NA PB108 F000007970/25781/20009021 F000007970
25781

I tried the below code
library(splitstackshape)
df2=concat.split.multiple(df1,"Plant.Item.Code","/", direction="long")
but got the Error
"Error: memory exhausted (limit reached?)"
When i tried strsplit() i got the below error message.
Error in strsplit(df1$Plant.Item.Code, "/") : non-character argument
Any help from you will be appreciated.
