Transform just one row to column

Hello, i've a problem with my data. Trying to work with timeseries and when i import my data it's like this :slight_smile:
Geo/time 2000 2001 2002 ....
Belgique x1 x2 x3
Bulgarie xa1 xa2 xa3
Tchéquie xb1 xb2 xb3
...
And i need :
i t
Belgique 2000 x1
Belgique 2001 x2
Belgique 2002 x3
Bulgarie 2000 xa1
Bulgarie 2001 xa2
...

How can i do ? I'm trying with t() but it's not working

Thanks for helping a begginer ^^

Hi @Hanz, could you please provide some data in format that is easy to copy/paste - you can see how to do this here: FAQ: What's a reproducible example (reprex) and how do I do one?

In the meantime, what you might need is the pivot_longer function from the tidyr package.

Maybe this example can clarify further:

library(tidyverse)
set.seed(1)
data <- tibble(country = c('A', 'B', 'C'), `2000` = rnorm(3), `2001` = rnorm(3), `2002` = rnorm(3))
pivot_longer(data, cols = -country, names_to = 'Year', values_to = 'some_metric')
#> # A tibble: 9 x 3
#>   country Year  some_metric
#>   <chr>   <chr>       <dbl>
#> 1 A       2000       -0.626
#> 2 A       2001        1.60 
#> 3 A       2002        0.487
#> 4 B       2000        0.184
#> 5 B       2001        0.330
#> 6 B       2002        0.738
#> 7 C       2000       -0.836
#> 8 C       2001       -0.820
#> 9 C       2002        0.576

I used dput to reproduce my data :

I've try to change years as vector but i failed, i'm trying with your answer (thanks ! :slight_smile:)

I've formatted your code. This prevents the chance the forum system will misinterpret parts as formatting, but it's also easier to read for everyone.

You can format code blocks in posts by putting a line with three accent marks before and after the code:

```
a <- 1 + 1
```

It's work, thanks a lot :smiley:
