Hi,
Try:
df = data.frame(currency_type = c("EURO_o_n", "EURO_o_n", "EURO_1w", "EURO_1w",
"USD_o_n", "USD_o_n", "USD_1w", "USD_1w"), rates = c(0.47, 0.475, 0.461, 0.464,
1.21, 1.19, 1.41, 1.43),stringsAsFactors=FALSE)
df$currency<-unlist(lapply(str_split(df[,1],"_"),`[`,1))
df$tenor<-unlist(lapply(str_split(df[,1],"_"),function(x)
{paste(x[-1],collapse="_")}))
df[,c(3,4,2)]
# currency tenor rates
#1 EURO o_n 0.470
#2 EURO o_n 0.475
#3 EURO 1w 0.461
#4 EURO 1w 0.464
#5 USD o_n 1.210
#6 USD o_n 1.190
#7 USD 1w 1.410
#8 USD 1w 1.430

Dear R forum
I have a data.frame
df = data.frame(currency_type = c("EURO_o_n", "EURO_o_n", "EURO_1w", "EURO_1w",
"USD_o_n", "USD_o_n", "USD_1w", "USD_1w"), rates = c(0.47, 0.475, 0.461, 0.464,
1.21, 1.19, 1.41, 1.43))
currency_type rates
1 EURO_o_n 0.470
2 EURO_o_n 0.475
3 EURO_1w 0.461
4 EURO_1w 0.464
5 USD_o_n 1.210
6 USD_o_n 1.190
7 USD_1w 1.410
8 USD_1w 1.430
I need to split the values appearing under currency_type to obtain following
data.frame in the "original order"
currency tenor rates
EURO o_n 0.470
EURO o_n 0.475
EURO 1w 0.461
EURO 1w 0.464
USD o_n 1.210
USD o_n 1.190
USD 1w 1.410
USD 1w 1.430
Basically I need to split the currency name and tenors.
I tried
strsplit(df$currency_type, "_")
Error in strsplit(df$currency_type, "_") : non-character argument
Kindly guide
Katherine
