Subject: bind data.frames seperately
Hi to all,
I would like to bind data1 and data2 (both are coming from an Excel
sheet) but only the data rows
using rbind will cause double names and value.
but I need only add the data.rows and the rest of the names and values
should be NA
value.1=c("a","b","c","d",5:54) # building similar data frame
like from excel
for (i in 5:54) value.1[i] <- NA #only to simulate the NAs
for the example
value.2=c(1:54)
for (i in 5:54) value.2[i] <- NA
data1<-data.frame(names=value.1, value=value.2,
data.row.1=c(1:54),data.row.2=c(1:54))
value.1=c("a","b","c","d",5:69)
for (i in 5:69) value.1[i] <- NA
value.2=c(1:69)
for (i in 5:69) value.2[i] <- NA
data2<-data.frame(names=value.1, value.2,
data.row.1=c(1:69),data.row.2=c(1:69))
By the way: Why are the NAs from name are changing from NA to <NA> after
the data.frame command?
Thank you for your help
Carmen
