[R] Need to insert various rows of data from a data frame after particular rows from another dataframe

[PIKAL Petr]

Hi.

 

„is not working“ is extremelly vague.

 

1.

What do you expect this code do?

 

for(cr in seq_along(dacnet_17$district)){

    match(arhar_18$district, dacnet_17$district)

}

 

See ?match and maybe also ?“for“ and try this

 

x <- letters[1:5]

y <- sample(letters, 100, replace=T)

match(x,y)

[1] 45 16 24 13 71

for(i in 1:3) match(x,y)

 

2.

rbind works as expeceted

 

arhar_18 <- data.frame(a=1:10, b=50, c=letters[1:10])

dacnet_17 <- data.frame(a=11:20, b=100, c=sample(letters,10))

df3=rbind(arhar_18,dacnet_17)

 

if your data has common column order and type.

 

To get more specific answer you need to ask specific question preferably with some data included (most preferably by dput command) and error message.

 

Cheers

Petr

Hi Petr,

 

I used r-bind but it's not working.

Here is the code:

 

arhar_18<-read.csv("D:/Ranjeet/IAMV6/input/yield/kharif_18-19_yield/Kharif_2018/arhar_18.csv")

dacnet_17<-read.csv("D:/Ranjeet/IAMV6/input/yield/dacnet_yield_update till 2019.csv")

 

for(cr in seq_along(dacnet_17$district)){

    match(arhar_18$district, dacnet_17$district)

}

 

df3=rbind(arhar_18,dacnet_17)

df3=df3[order(df3$district,df3$year),]

x<-write.csv(df3,"df3.csv")

view(x)

Hi.

>From what you say, plain "rbind" could be used, if the columns in both sets
are the same and in the same order. After that you can reorder the resulting
data frame as you wish by "order". AFAIK for most functions row order in
data frame does not matter.

Cheers
