Need to insert various rows of data from a data frame after particular rows from another dataframe
Hallo Ranjeet You got some other answers which revealed that the original data were problematic. The error suggests that you have different number of columns in each data frame. df1 <- data.frame(a=letters[1:5], b=1:5) df2 <- data.frame(a=LETTERS[1:5], b=letters[1:5], c=1:5)
rbind(df1, df2)
Error in rbind(deparse.level, ...) : numbers of columns of arguments do not match So for rbind to work, both data frames should have the same number of columns and also the correct column in correct place. If it is not the case, you could use merge, but the missing values in common column, (in this case b) will be filled by NA. df2 <- data.frame(a=LETTERS[1:10], b=letters[1:10], c=1:10) merge(df1, df2, by.x="a", by.y="b", all=TRUE) a b a.y c 1 a 1 A 1 2 b 2 B 2 3 c 3 C 3 4 d 4 D 4 5 e 5 E 5 6 f NA F 6 7 g NA G 7 8 h NA H 8 9 i NA I 9 10 j NA J 10
If you managed to get both, kharif and dacnet into R it would be worthwhile to show at least the structure of your data by sending result of str(kharif_18_19) and str(dacnet_17) Structure should be the same. Or better to send a chunk of the data as output from dput(head(kharif_18_19),20) and dput(head(dacnet_17),20) so everybody could inspect directly how those objects in your R look like. Cheers Petr And BTW, do not use HTML formating, it could scramble your email as r-help list is plain text only.

That means no difference in columns.

Hi Pikal, Now I have formatted the kharif data file in the same format as it is in the dacnet filecode:. However, "http://district.noclick_id" and "http://state.id " columns have "N/A" data that are appearing. If I use merge "rbind" function, it still throws this error: "Error in rbind(deparse.level, ...) : numbers of columns of arguments do not match" code: df3=rbind(kharif_18_19,dacnet_17) df3=df3[order(df3$district,df3$year),] x<-write.csv(df3,"df3.csv") view(x)

Hallo, I do not understand what you really want and you do not help much. No error, no data, vague description of your problem, no effort to explain it better. Only you can see your data, only you can see the error message so we are clueless.

But here I am struggling to bring the 2nd dataframe in the same format as the 1st one.

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 Petr
